Description Mark Bolhuis 2024-11-22 07:16:02 UTC

SUMMARY
The application menu bar is placed incorrectly.

STEPS TO REPRODUCE
1. Disable any display scaling
2.  Configure the title bar to include the application menu. 
System Settings -> Colors and Themes -> Window Decorations -> Configure Titlebar Buttons
3. Put the window is different places, and click the application menu on the titlebar.

OBSERVED RESULT
The menu is placed at approximately (2x, 2y) where (x, y) is the position of the button. 

EXPECTED RESULT
The menu should be placed at the button.

SOFTWARE/OS VERSIONS
Operating System: Arch Linux 
KDE Plasma Version: 6.2.3
KDE Frameworks Version: 6.8.0
Qt Version: 6.8.0
Kernel Version: 6.11.9-arch1-1 (64-bit)
Graphics Platform: Wayland
Processors: 28 × Intel® Core™ i7-14700K
Memory: 30.5 GiB of RAM
Graphics Processor: Mesa Intel® Graphics

ADDITIONAL INFORMATION
When display scaling is enabled, fractional or integer, the error factor is no longer 2, but changes with the scaling factor.
From a rough observation the menu is placed at approximately (1.5x, 1.5y), for 1.25 scaling.

Do you have multiple screens? If so, this is Bug 413771.

Comment 3 John Kizer 2024-11-25 21:33:38 UTC

On my end at least, I only have one display - I do have Nvidia graphics, but I wasn't thinking in that direction at first since the reporter has Intel graphics.

I only have one screen.
And the behaviour I see isn't quite the same as what is described in that bug report..
I'll do some more testing.
