Crash on launch on wayland (sway) with mixed-scaled dual monitor setup

[nidico]

Description

Since a couple of weeks / months, element-desktop-nightly fails to start on wayland (sway 1.8.1) - the window opens and immediately closes.

Today I took the time to investigate this further.

Launching element-desktop-nightly --enable-features=UseOzonePlatform --ozone-platform=wayland immediately crashes with the following error message:

[14094:0416/110801.824532:ERROR:wayland_event_watcher.cc(39)] libwayland: xdg_wm_base@15: error 4: wrong configure serial: 6263

This only (and always) happens on a specific dual monitor configuration (one monitor scaled, another monitor unscaled) when launching element on the right (no matter if the left or the right monitor is scaled!) monitor. Launching element on the left monitor and moving it afterwards does not cause this issue. (<- Simple Workaround!)

This is a sample sway config causing the issue:

output HDMI-A-1 pos 0 0 res 1920x1200
output DP-1 pos 1920 0 res 3840x2160 scale 2

As I assume that this is an electron issue (also reported for chromium: arch bug tracker, nix bug tracker, upstream), I tried to replicate the issue with other versions and other apps:

• element-desktop-nightly 2023041501 (current nightly, electron 4.0.0) has the issue (this report).
• element-desktop 1.11.29 (current stable, electron 23.1.3) behaves similarly, but not as reliably (sometimes crashes only after a couple of seconds, also on the left monitor) and doesn't output above error.
• signal-desktop 6.14.0 (electron 22.3.5) doesn't have that issue.
• wire-desktop 3.30.3018 (electron 21.3.3) doesn't have this issue.
• chromium 112.0.5615 also has this issue - same error message as above.

Unfortunately I wasn't able to provoke this issue with the much simpler electron/electron-quick-start with either electron 24.0.0 or 24.1.1.

+1ing this. I'm experiencing the exact issue and behavior described on Manjaro Sway. Any browser based on a chromium version greater than 110.0.5481.177 crashes for me if launched on a monitor other than the left most monitor. I have similar multimonitor set up. scale 2, 1, 1. Can provide more details if needed/wanted.

Update with current versions:

• Stable element-desktop 1.11.33 uses electron 24.3.1 and has this issue (crashes when opened in right monitor)
• element-desktop-nightly 2023061901 uses electron 25.1.0 and doesn't start up at all in wayland native, even with a non-dual-monitor setup - therefore I filed a separate issue - see Nightly (using electron 25.1.x) crashes on launch on wayland (sway) #1026

Update with current versions:

• Stable element-desktop 1.11.34 uses electron 25.1.0 and doesn't have this issue (or Nightly (using electron 25.1.x) crashes on launch on wayland (sway) #1026)!
• element-desktop-nightly 2023062901 uses electron 25.2.0 and doesn't start up at all in wayland native, even with a non-dual-monitor setup (issue Nightly (using electron 25.1.x) crashes on launch on wayland (sway) #1026)
