Oxygen window button artifacts in 160% scaling
DESCRIPTION
With scaling factor set to 160%, window buttons (close, maximize, ...) buttons
has some rendering or scaling artifact, mostly in the upper side, but some also
on the left side. See the attached image.
They also show up with 135%, 165%, but not with 150%, 175%, 180%, 200%.
STEPS TO REPRODUCE
1. Use Oxygen decoration theme in System Settings
2. Choose 160% as scaling factor
OBSERVED RESULT
Artifacts in window buttons.
EXPECTED RESULT
Window buttons should be perfect circle.
SOFTWARE/OS VERSIONS
Operating System: Arch Linux
KDE Plasma Version: 6.8.0
KDE Frameworks Version: 6.31.0
Qt Version: 6.12.0
Kernel Version: 7.2.11-arch1-1 (64-bit)

Graphics Processor: AMD Radeon Graphics
ADDITIONAL INFORMATION
I know 160% scaling factor sounds pretty weird, but it has a nice property that
150% and 175% do not have: it produces integer logical resolution for many
common physical resolutions:
- 3840 x 2160 physical → 2400 x 1350 logical
- 2560 x 1600 physical → 1600 x 1000 logical
- 2560 x 1440 physical → 1600 x 900 logical
- 3440 x 1440 physical → 2150 x 900 logical
- 2800 x 1800 physical → 1750 x 1125 logical
- 2880 x 1800 physical → 1800 x 1125 logical
So it could probably see some love 0_0
