Reproduction steps:
1. Have at least two monitors for testing
2. Make sure the secondary display is set to the left of the primary display
3. Create and open any new project
4. Drag the Editor Window from the primary display to the secondary display
5. Observe the Editor

Expected result: Editor Window is rendered with no artifacts/black spots
Actual result: Parts of the Editor are completely black, and resizing does not work on those parts of the Editor or it causes significant glitching

Reproducible with: 6000.4.0a2
Not reproducible with: 6000.0.59f1, 6000.2.8f1, 6000.3.0b6, 6000.4.0a1

Reproducible on: Windows 11
Not reproducible on: no other environments tested

Notes:
- Does not reproduce if the secondary monitor is to the right of the primary display
- Issue was reproduced with this display setup: Primary display - 3840x2400, 300% scaling, Secondary display - 2460x1440, 175% scaling
- If, after 4th step, the Editor layout is reset to Default, even more glitching can be observed (sometimes that glitching happens even without this step)
