Display slightly too big

I have completely the same problems. With 2.8, this was not the case, there is only in 2.9 and 2.10, a buster and a bookworm.
I had to go to resolution 1280 * 1024, but I don't like it - small icons (((

I am another one with same problem
1024x768 , debian bookworm , 2.9

I made some modifications so gmoccapy always start in windowed mode, then I switch to fullscreen and then it works fine. Else buttons go right and I cannot click it. 

Seems there is a gmoccapy bug with switching fullscreen mode on startup on small resolutions. Once window is fully open and initialized, problem disappears.

I just tried and it is easy to repeat in VirtualBox bookworm-2.9 linux install
- set resolution 1024х768
- start gmoccapy 4axis sim config (allow copy config to home dir)
- enable fullscreen in settings
- exit linuxcnc
- restart gmoccapy 4axis sim config from home dir
- buttons are out of screen

I've found a naive workaround, not sure if it is acceptable as common solution, but works for me.

Edit file /usr/bin/gmoccapy
find line

replace to

find lines

replace to

what does it do? it schedules a timer to enable full-screen with 3 seconds delay and it works like a charm now.

Your suggestion worked great! I changed the file as you describe, except that I made the delay 2 seconds.

Thanks!

I have a fix for this. See github.com/LinuxCNC/linuxcnc/pull/2831 .
The solution is very simple - just removing one property in the glade file, but it took me a while to get to this point.
The background:
The button "World Mode/Joint Mode" is displayed optional, so there is a placeholder label if that button is not shown. The problem is that at the time the GUI is created (started), the button and the label are active and that make the window too wide to fit 1024 px. The fix is just to have this button hidden at start.
 

Interesting, I'm upgrading gmoccapy.py and gmoccapy.glade as described at github. Nothing changed. Window is still too width.
