Sublime Text 4 freezes on monitor layout change

#1

Whenever the monitor layout changes (insert/remove Notebook into/from docking station), some Sublime Text windows freeze and about the lower third of the frozen window is either black or shows the desktop wallpaper (even if there are other windows behind it). The issue has been there for quite some time and Sublime Text is the only application that shows it.

Sublime Text 4 (installed from AUR) on Manjaro Linux with KDE Plasma desktop.

Any idea what might be the issue? Or where I could start looking?

Edit:
Changing the option hardware_acceleration frome none to opengl causes sublime text to crash instead of the freeze.

Are you using X11 or Wayland?

I’m using X11.

Does it still happen if you use wayland?

I’ve tried it and temporarily switched to Wayland and it did not happen there.

This is likely a bug with KDE or GTK then. You could try attaching a debugger with opengl enabled and see where it crashed.

How can I do that?

With gdb installed you can run gdb --args /opt/sublime_text/sublime_text --multiinstance --debug. When the prompt appears type r to run Sublime Text. When the crash happens you can type bt into the prompt to get a backtrace.

I did not get it to reproduce reliably at first. I have two external screens connected to the notebook (with the notebook screen off), the first one and the notebook have the same resolution, the second screen has a different one. It seems that the problem only occurs when I have a Sublime Text window on this second screen.

Here is the backtrace (although it “just” froze even with the opengl option).

Is this an issue with GTK then?

That certainly looks like a GTK issue. What exact version of GTK3 are you using?

My GTK3 version is 1:3.24.38-1

I guess I’ll report it to GTK then. Thank you for your help.
