Created attachment 107688 [details] hinting glow The hinting glow is wrongly sized on autohide panels. see attached screenshots
Created attachment 107689 [details] actual panel size
Could be related to the fact that this is a high dpi screen and I have set the scale factor to 2x
It's not meant to be a glow for the panel, it's kwin showing there's an edge activation. You see the same one if you have edge activated desktop switching; autohide panels re-use the same mechanism.
So this issue can be safely closed?
Comment #3 says it works as intended.
