Created attachment 82536 [details] screenshot On my SNB laptop (running xfce with no composition manager), when scrolling within an application which has a window on top, the background application isn't re-painted with 2.21.12. Instead, the content of the top-level window is "scrolled". Please find a screenshot of the issue attached. Side note: Current git ( 3f3071c6c91c3907cb0fecf2f69a995feefe7956 ) is completely broken on my system. Scrolling doesn't seem to honor clipping and I get frequent crashes.
Describe the crashes, please. I thought I had the scroll regression understood, but you make it sound like I just opened a can of worms instead.
