GIMP Window Changes Size on Any Action

[Jeremy_Ray]

GIMP is 3.0.6, OS is Kubuntu 24.04

Here is how it is supposed to look, crammed into the screen space of my little Cintiq 12WX - 





Any action at all causes the main window to shrink down like this - 





What could be causing it to do this?  

Incidentally, I tried the option to merge the GIMP menu bar with the system menu bar.  I then turned it off, which didn't turn it off.  I then reset the preferences, which didn't turn it off.  I then uninstalled GIMP (using snap, which I installed GIMP with), shut down the computer, turned the computer back on and reinstalled GIMP.  That didn't restore the system menu bar either.  I don't know if that has anything to do with this problem or not. 

Incidentally, the rulers and status bar should be turned off, but they've stuck around anyway.

I am using kubuntu 24.04 on a laptop display 1920x1080  

(1) Merging the menu bar Edit -> Preferences -> Image Windows should toggle on and off, it does for me. If it is stuck you might have to delete your user profile and start from new.

(2) I know nothing about your Cintiq 12WX  except it has a 1280 x 800 display.  KDE has all sorts of options.  One is fixing window sizes, I have my Gimp (s) set to 1280 x 720 for video capture but I do not know if that is reflected in the Cintiq 12WX.

You could try it with Gimp in multi window mode: It is a right click in the Gimp Title bar and follow the menus. Looks like this:

   

One snag for Gimp multi windows mode, it only really applies to one window.  might be worth a try.
