Description Antti Savolainen 2024-10-19 02:00:59 UTC

SUMMARY
Demonstrative video: https://youtu.be/mqC5D9vFKa4
If I open two dolphin windows and tile them side by side, the one on the right will have its hamburger menu submenus stack on top of each other. This is reproducible with native quicktiling as well as with Krohnkite. I have a multimonitor setup and it might be a cause in case anyone is unable to repro.

STEPS TO REPRODUCE
1. Open two dolphin windows
2. Tile them side by side
3. Open the hamburger menu on the rightmost window

OBSERVED RESULT
The submenus will stack on top of each other

EXPECTED RESULT
The submenus should place themselves next to each other.

I'm able to reproduce this in git-master with just one screen (laptop native)
Plasma git-master
Dolphin 24.11.70

The problem isn't when 2 applications are opened, just move the window on the right, submenu will overlap the parent one.
I will move issue to KxmlGui, no problem with Dolphin, (Kate is also affected), KHumberger menu is correct also, Falkon creates it without KxmlGui (sets main window  as parent) and no overlap.

Comment 3 Anthony Fieroni 2025-03-22 12:12:23 UTC

Steps to reproduce:
1. Open Dolphin
2. Move window on the right edge (NOTE this)
3. Click hamburger menu -> create new -> new menu overlaps submenu, when submenu is wider than parent you cannot navigate to parent menu item below

This is specific issue when KHumberger menu is created through KxmlGui window (when it's in rc file) Falkon uses KHumberber menu as raw menu just put Falkon main window as parent and submenus doesn't override the parent one. Also KxmlGui window works correct (no overlap) when window is fullscreen (this makes things weird)
