Description rucltsdata 2025-04-26 10:38:15 UTC
Description:
I does this only if it it occupies the margin between the 2 screens (aproximatley the last 10th of the screen). If I keet it outside this region it works properly. I have set the additional screen to be the mai one.

Steps to Reproduce:
1.Connect an additional screen with a different resolution than the laptop's screen, be sure it is conected like  an additional screen, for ease of reproduction, let it be on the right side of laptop's screen, make it the main one.
2. Open LibreOffice calc and make it fullscreen on the laptop
3. Try to select different cells or open the dropdown menus and look at the CPU load
4. Put LibreOffice on the right side of the laptop screen, now it should work properly

Actual Results:
LibreOffice calc is using too much CPU and is not showing the selected cell and dropdown menus

Expected Results:
It works properly


Reproducible: Always

Could not reproduce with my dual screens. I did not observe any CPU load differences in task manager. This may be a hardware dependent issue.

Still waiting for this info. Would also be interesting to hear how 25.8 behaves.
