Attachments: Blurry menu

Description Tech-Tac 2026-01-18 09:57:37 UTC 
SUMMARY
Context menus in the process lists in system monitor have blurry icons and borders, they don't seem to snap to the pixel grid of the screen

STEPS TO REPRODUCE
1. Open system monitor
2. Right click a running task
3. Repeat a few times while clicking in different positions

OBSERVED RESULT
The icons on the menu look visibly blurry (tested on a standard/low DPI monitor)
It also slightly changes if you open the menu from a different position

EXPECTED RESULT
Look not blurry I guess

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Arch
KDE Plasma Version: 6.5.5
KDE Frameworks Version: 6.22.0
Qt Version: 6.10.1

Blurry menu

Also notice how the text look crisp compared to the icons and how the border of the menu isn't a perfect 1 px solid line
Comment 2 Tech-Tac 2026-01-18 09:59:57 UTC 
I forgot to mention that I don't have any scaling options turned on, I'm on 100% scaling in native resolution.
Comment 3 Arjen Hiemstra 2026-01-19 09:24:23 UTC 
Huh, I never noticed before, but you're right, there does seem to be something off with the icons.

faces: Round context menu popup location for tables

Without rounding we potentially place the menu at fractional coordinates
which results in slight rendering issues due to pixel misalignment.
