Startup Crash - Gnome 46 w/ Scaling

[peteigel]

What Operating System(s) are you seeing this problem on?

Linux Wayland

Which Wayland compositor or X11 Window manager(s) are you using?

Mutter (Gnome 46)

WezTerm version

20240203-110809-5046fc22

Did you try the latest nightly build to see if the issue is better (or worse!) than your current version?

I tried building from source. It launches fine at any scale, but doesn't show window decorations. I think I had built it successfully from source before.

Describe the bug

Wezterm Flatpak crashes on Gnome 46 display scale is not 100%.

I used wezterm with 125% scaling daily in Fedora 39, and it won't start on Fedora 40. I was able to reproduce at both 125% and 200% scale.

To Reproduce

• Install WezTerm flatpack on Fedora 40
• Set display scale to a value other than 100%
• Launch WezTerm

Configuration

no config

Expected Behavior

App launches properly

Logs

wl_surface@44: error 2: Buffer size (12x575) must be an integer multiple of the buffer_scale (2).

Anything else?

I see the same thing, Gnome 46 on Fedora 40, with 2x scaling on my laptop display (fractional scaling is enabled, though, to run in 1.5x docked):

wl_surface@44: error 2: Buffer size (12x613) must be an integer multiple of the buffer_scale (2).

Disabling Wayland in my config allows WezTerm to start for me on Gnome 46:

config.enable_wayland = false

Alternatively, start WezTerm with the WAYLAND_DISPLAY environment variable set to 1.

Same issue for me on Hyprland. Starting on non-scaled display is fine, but not on scaled. Moving wezterm window from non-scaled display to a scaled one also causes crash.

Please try with the very latest nightly build, as a lot of wayland changes have recently been merged

Built latest main (8fa4ba9), still same error.

Also tested on Gnome 46.1, both 2024-04-29-102818-0184e88e and the latest source build are working fine on scaled display 🤔 So probably my issue is Hyprland (or wlroots?)-specific

[l-c-g]

I tested the AppImage nightly downloaded today and version wezterm-20240505_232355_e6db4408-0.x86_64 from the COPR repo. Both start on my Fedora 40/Gnome 46 installation with 200% scaling, so my issue with Gnome 46 appears to be fixed.

Nightly AppImage fixes the issue.

[peteigel]

In the latest main scaling is fixed, but window decorations missing. I've reproduced that both building from source and from the latest nightly in the COPR repo, I suppose I can open a separate issue for that if that would be helpful.
