recently I moved to gnome 42 and found that shortcut ctrl+alt+s makes current window fit to a specific window size such as 360x654, 720x360 etc.
I tried to redefine the shortcut and dug into settings menu but could not find any matching shortcuts. I guess it is hidden but not sure.
How can I find the definition or remove it?
Execute these commands in your terminal:
gsettings set org.gnome.shell.extensions.screenshot-window-sizer cycle-screenshot-sizes "[]"
gsettings set org.gnome.shell.extensions.screenshot-window-sizer cycle-screenshot-sizes-backward "[]"
That did the trick for me.
I resolved this issue by deactivating the "Screenshot Window Sizer" Gnome extension by fmuellner.
I didn't activate this stupid plugin... I was wondering, why I can't enter IntelliJ IDEA Settings by using CTRL+ALT+S
Now it works for me...
