Wayland + Nvidia: rerun --skip-welcome-screen causes Rerun to hang on launch

[jleibs]

So far Rerun works fine in all other contexts, however when skipping the welcome screen the viewer hangs consistently.

Happens in either debug or release.

Output:

Some window decorations show up but the app is otherwise totally unresponsive:

In debugger, everthing paused except:

[emilk]

Have you tried attaching a debugger to get a callstack?

[jleibs]

Confirmed this also repros in the egui demo app (but not egui hello_world app)

[jleibs]

Turns out this (and many other things) were fixed by downgrading the nvidia driver from version 545 -> 535

[jleibs]

This appears to be related to be caused by: gfx-rs/wgpu#4775

Also appears to be fixed on latest (trunk) wgpu with the nvidia 550-drivers as of gfx-rs/wgpu#4967 so we can probably close after next wgpu (and subsequent egui releases).
