Comment 4 TraceyC 2025-07-07 20:43:47 UTC

I'm not able reproduce this on Fedora 42 with Plasma 6.4.2 or with Plasma built from git-master
or with Neon User with Plasma 6.4.2

Are you able to reproduce this on your system with Plasma 6.4.2 or later?

> screen arrangement

that's the problem

Comment 8 TraceyC 2025-07-30 19:01:22 UTC

Thanks for the screenshots. I see how the menu looks detached from the menu bar and doesn't contain all the entries.
I checked on git-master with a similar display setup using Audacity but wasn't able to reproduce the bug.

Laptop 1920 x 1080 @ 100% on the right
External monitor 3440 x 1440 @100 % - connected via HDMI cable

I also was unable to reproduce with Plasma 6.4.3 with another laptop

Laptop 3840 x 2400 @ 150%
1 external monitor 3440 x 1440 @100 % - connected via USB-C dock over Displayport

I'll leave this open in case someone else can reproduce. 
This could be a variant of a long standing report - bug 458280 - which has a lot of duplicates with slightly different symptoms

Comment 9 TraceyC 2025-07-30 19:03:13 UTC

I meant to reference bug 413771

godot kde from git master

I was able to reproduce the bug with kde 6.5 from the master git branch.
But the bug appeared not at the top of the tall screen, but at the bottom.

try to rearrange monitors, not scaling

Comment 12 TraceyC 2025-07-30 20:24:12 UTC

I'll set this to confirmed since you were able to reproduce in git-master
