Next Release Checklist

[wez]

BEFORE YOU COMMENT: please avoid duplicating information from other comments to avoid overwhelming this one.
Prefer to use a thumbs up instead of a me-too comment.

We're overdue for making a new release.
Here's what's on my mind as release gating issues, and I need your help to check these off.
So if you are interested in having a new stable tag, please help by running through the list below and giving some feedback on the state of these things for your system:

• Verify that Wayland support isn't an obvious regression since the last stable release.

  • Wayland support was essentially rewritten by the community, and since I don't use wayland, I don't have sufficient context now to understand where it has problems either in the code or due to compatibility.
  • If you are a Wayland user, and you are using a wezterm nightly build from October 2024 or later and having a good experience, please comment below with the name of your compositor and DE to say that it is as good as or better than the prior stable release.
  • If there is already a comment describing your environment, instead of posting a duplicate, please give it a thumbs-up reaction to "vote" for it if it is working well for you.
  • If it isn't working working as well or better than the prior stable release, please reference an issue that describes the problem and comment below.

• Verify that the default configuration doesn't crash out.

  • Run wezterm -n on your system to launch it without your config. Does it successfully launch and display text with no artifacts or blocks for glyphs?
  • If not:
    • try changing the front_end setting to see if that is better:
    • wezterm -n --config "front_end='WebGpu'"
    • Please find/file an issue reporting the outcome of both the default and webgpu, along with information about the environment. If the behavior is a regression since the prior stable release, reference that issue here.

• Confirm that we're building for the current batch of OS/distros

  • Add CI for Fedora Linux 41, drop Fedora Linux 38 as it's EOL #6156
  • Alter copr spec file for Fedora 41 and Rawhide #6200
  • Others? Please comment here

• Other misc issues:

  • Fix alternate-screen scrolling #6186

KDE Plasma 6 (Wayland) working great for me on nightly.

[jankatins]

I'm on Gnome 46/Mutter with Windowing system Wayland (fedora 40 workstation, up to date until yesterday), using wezterm 20241027_002434_14ad1937.

Stuff which I "notice" (I seem to remember that it worked sometime before the rewrite or when I was still on macosx). This is all with config.enable_wayland = true or not having that config set at all:

• I don't have an additional title bar (which is fine-ish) and double click on the tab bar to maximize does not work (which is bad). I added that as a config in Gnome: Gnome: Allow double click on title bar to maximize the window #2831
• I don't have min/max/close buttons in the tab bar, which I kind of think where there earlier? As there is also no title bar, I need to use 'win+up' to toogle maximize (which I configured in gnome)
• I cannot move the window anymore: Title Bar is missing if config.enable_wayland = true #6296
• I use a gui-startup event handler to window:gui_window():maximize() -> my window still comes up unmaximized -> Prob Maximize is not working and fullscreen is not fullscreen #6203
• If I configure config.window_decorations = "INTEGRATED_BUTTONS", I get an additional (black and completely different form the rest of the windows on gnome) title bar with the min/max/close buttons and max and close work. I can also move the window around when I start dragging on that new title bar. Still, double click on that title bar to maximize does NOT work and the min button also does NOT work: Using INTEGRATED_BUTTONS decorations on Linux, the minimize button is nonfunctional #6086 (this might be a general error, as the issue was reported on x11)
• With config.window_decorations = "INTEGRATED_BUTTONS" The full screen window "overflows" at the bottom. The window overflows bottom of screen #6318

If I run with config.enable_wayland = false, I have a (grey, like the rest of GNOME) additional title bar with a single close button, I can move the window around, even when I was in fullscreen, it starts in full screen, and the window overflow problem is also gone.

So all in all: Using config.window_decorations = "INTEGRATED_BUTTONS" and some additional config.window_padding = {...} I can live with using wezterm (with config.enable_wayland = true) as my daily driver, but I'm also currently embarrassed to show my terminal window to colleagues who use warp or alacritty or recommend it to ppl. who would usually benefit from a cross platform terminal :-(

Relevant Gnome config:

gsettings set org.gnome.desktop.wm.keybindings maximize "['<Super>Up']"
gsettings set org.gnome.desktop.wm.preferences action-double-click-titlebar 'toggle-maximize'

There's a regression on Sway 1.10.
Nightly works for me on Sway 1.9, but I'm guessing the new wlroots-0.18 in 1.10 broke parts of the WezTerm Wayland implementation.

	WezTerm stable	WezTerm nightly (f847bd28)
Sway 1.9	❌ Logs	✅ Logs
Sway 1.10	❌ Logs	❌ Logs

Tested on NixOS unstable, Linux 6.11.5, x86_64-linux.

All logs are collected via:

WAYLAND_DEBUG=1 WEZTERM_LOG=window::os::wayland=trace cargo r --release --bin wezterm-gui -- -n --config "front_end='WebGpu'"

It's worth mentioning that [email protected] initially renders blurry text, which goes away after scaling/moving/maximizing the window once. But overall, I had a pretty reliable experience on Wayland on Sway 1.9.

---

As for Sway 1.10:

I've tried to chase down the error with a debug build & debugging via CodeLLDB, all I could gather from it, is that it crashes around here.
It seems to crash after a few iterations, so it makes debugging a bit frustrating; I'm happy to dive back in tho.
Sometimes it also doesn't crash, but "hangs", in that it logs loading the config, and rendering the cursor block etc, but simply won't render the terminal window. I'd say that happens on about 1/4th(?) of the launches.

wezterm 20241031_235112_0983ae90
Fedora 41 - Gnome 47 - Wayland

• I would say the current nightly is much more stable than the current release (the current release wont even start anymore on my system). I am having the following issue with the current release, seems to be fixed in nightly. Weird issue when using wezterm on gnome wayland #6191
  I remember switching to the nightly version, because the release version kept on crashing all the time (Probably this was also related to fractional scaling)

Probably Regressions:

• WezTerm behaves a bit buggy with fractional scaling enabled. When I open WezTerm on my Primary Monitor (150% Scaling, 3840x2160 Resolution) Wezterm has no icon in the dock where the open apps are displayed and is shown as Unknown Application. If i open WezTerm on my secondary Monitor (100% Scaling, 1920x1080 Resolution) it works fine.
  
  Screenshot of Gnome Looking Glass Debug Tool (Alt + F2 - type lg). The First Application is WezTerm on the Monitor without Fractional Scaling, Second with Fractional Scaling (150%). I noticed that when opening the app, the icon is correct for a short time, but WezTerm immediately closes and reopens, only that the icon no longer works. This, closing and reopening behavior also happens if i move the Terminal from one Screen to the other and change focus to another window (it closes and reopens on the monitor on which my mouse is located at the time).
  WezTerm has no icon under Wayland when using fractional scaling (fractional-scale-v1) #6081
  I don't remember that happening in the last release, but i can not verify that anymore, because the current release is not starting anymore on my system.

• When using config.window_decorations = “RESIZE” with a high dpi screen, the client-side window decorations do not match the size of the terminal (at least with Gnome, which does not implement server-side window decorations). Also, every time the window loses or gains focus, the window changes size.
  Wezterm creates crazy large window on Wayland in Fedora 40 #5360. Also don't remember this happening in the last release.

Thanks for commenting folks. From a triage perspective, what I care about here in the context of this issue is:

• Would releasing nightly now be worse than the prior stable release?

I don't want this issue to an umbrella for current bugs: those can all continue to live in the issue tracker.

So please review the comments you have made and if the issues are also present in the prior stable release, please edit your comments to elide that information from here.

I want to use this issue as a point of triage for getting wezterm-regressions-in-behavior-vs-its-last-stable-release resolved, and if it just duplicates general bugs it is not helpful.

Thank you!

Fedora 41 - Gnome 47.1 - Mutter 47.1 - Wayland

• From what I feel the night version is a bit more stable(less crash), but in terms of UI it is a clear regression compared to the last release version 20240203_110809_5046fc22. Window resizing doesn't work in the night version as part of the regression.

config.animation_fps = 60
config.front_end = "WebGpu"
config.window_decorations = "INTEGRATED_BUTTONS"
