Opening new window from Gnome launcher crashes all windows on 200% scaling

[mcheshkov]

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

Linux Wayland

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

Mutter

WezTerm version

20241001_010643_d40c3b63

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

Yes, and I updated the version box above to show the version of the nightly that I tried

Describe the bug

When I try to open new terminal window from Gnome launcher it crashes whole app.
If I start first instance from terminal, and then try to middle click in launcher I can see a message about scaling before crash

18:15:01.856  ERROR  wezterm_mux_server_impl::local > writing pdu data buffer: Broken pipe (os error 32)
wl_surface#30: error 2: Buffer size (656x457) must be an integer multiple of the buffer_scale (2).
Protocol error 2 on object wl_surface@30: 
18:15:02.066  ERROR  wezterm_gui                    > running message loop: Protocol error 2 on object wl_surface@30: ; terminating

But when I try to open new window from terminal (by executing wezrem) it does not crash, there's no message about buffer_scale, only about pdu data buffer

ERROR  wezterm_mux_server_impl::local > writing pdu data buffer: Broken pipe (os error 32)

I have 200% scaling. When I turn it back to 100% everything works as expected.

Also strangely related
In 100% scaling new windows have correct window name and icon.
On 200% windows are named "Unknown", and have unknown app icon.

To Reproduce

1. Use Gnome with 200% desktop scaling
2. Start wezterm
3. Open new wezterm window with middle click in bottom panel or launcher

Configuration

no config

Expected Behavior

New window opens without crashing
