Also note I currently use https://github.com/sebcrozet/kiss3d with the same setup and it works fine |
@mchhoy thank you for logging this issue! So far fairly in the dark what could cause this, haven't seen this crash so far. Thank you! |
Erm some other error now .. also I forgot to note that I am in a docker container. Git commit 6c2b291

☝️ Both issues should be fixed on latest |
Previously I couldn't build from the workspace root as the web viewer crate didn't compile (maybe because there is no browser available or something) Anyway now it works :)
But without WGPU_BACKEND=gl

BTW the error when building the workspace root instead of

BTW this is the GDB backtrace

It's a bit concerning that you're getting a segfault, wgpu should manage to detect that the Vulkan backend is not suitable and bail out before getting into a hard crash. So this is still a bug on the wgpu side of things, unclear though if it is a bug is in the lavapipe vulkan implementation. Given though that there's now a viable workaround (albeit given your screenshot the gamma-curve is wrong..) and the target is outside of what we're currently supporting (we only have limited support for software rasterizers like lavapipe) For posterity: The workaround is to run with the opengl backend, via
Can you check that |
Describe the bug
To Reproduce
Steps to reproduce the behavior:
Use the following sshd_config, but use a new port:
Then
Then on the client
ssh [address] -X
cargo install rerun
WINIT_UNIX_BACKEND=x11 rerun
(I tried this idea rust-windowing/winit#305)
Expected behavior
X11 forwarding should show the screen on the client
Desktop (please complete the following information):
Workaround exists: Enforce using gl backend using
WGPU_BACKEND=gl
