Stuck pixels/artifacts at screen edge when using display scaling

[Roger-Roger-debug]

Hyprland version

0.48.1

Regression

Before commit 6967a31 this issue didn't happen.

Describe the bug

I've got two displays with a resolution of 3440x1440 and 2560x1440 and both have a scaling of 1.33333. The color of my window borders will "stick" to the last row and column of pixels. This used to happen with the cursor as well, but I can no longer reliably reproduce that after updating from 0.46.2 to 0.48.1.

Changing the display scaling down to 1 and then back to 1.33333 while hyprland is running fixes the issue.

I tried recording my screen but it doesn't show up with wf-recorder.

Something that might be related is that games report the screen resolution as 3439x1439, I guess that's the same row and column missing that doesn't get repainted in normal desktop usage.

Reproduction steps

1. Have a monitor with a high resolution
2. Set the scaling to 1.33333
3. Have the border color/shadow touch the screen edge
