Hi,
I have tried a workday with wayland (sway) and am using QtCreator. I
observe, after running it for 1-2 hours QtCreator crashes. (I had 3-4
crashes today.) When it happens, I am using its GUI to do something in
its text editor, and then it suddenly disappears. I mean, I am not
switching monitors or any of such extreme, just usual flow.
I am using QT_QPA_PLATFORM=wayland, and the crash happens in
QScreen::availableGeometry(), see backtrace[1].
The versions are: QtCreator 4.14.0-4, QtCore 5.15.2-3 (default in
archlinux nowadays).
Did you observe such, either with QtCreator or any other Qt app? Is
there a bug about it?
Robert
