Description ratijas 2022-07-08 19:06:02 UTC

SUMMARY

Basically, geometry sizes are not rounded, which may cause jumpiness when a window is dragged little-by-little across a screen.

STEPS TO REPRODUCE
1. Open a window which doesn't take the whole screen.
2. Drag it a little bit

OBSERVED RESULT

Window has moved, but also its size increased or decreased by a pixel.

EXPECTED RESULT

Window should move without changing its size.
