Created attachment 187942 [details] outline gap SUMMARY If I move any app from the secondary screen to the primary, the outline gets a one pixel gap. The secondary screen has fractional scaling, the primary doesn't.

Does it still happen with a scale factor of 100% or 200%?
(In reply to Nate Graham from comment #2) > Does it still happen with a scale factor of 100% or 200%? No, only fractional scales. Weirdly, if the scale factor is under 150%, the gap will be on the display with the 100<scale<150. (in my setup output 1) If the scale factor is higher than 150%, the gap will show up on the display scaled to 100% (Output 2)
