--- Comment #3 from Patrick (volunteer) <[email protected]> --- I can reproduce this in my local master build. What caught my eye is that in your video while using the nightly build, I see rapid drawing of thin white vertical lines in the column headers when you dragged the mouse rapidly right and left. So this looks like some drawing timer is not getting a chance to run. If I remove commit 5a38e4f9798c5ff247aa57581adf2671485627fd, the vertical lines in the cell area keeps up with the thin white vertical lines in the column headers so I am guessing that the Skia "flush to native window" timer causes this bug when that timer's priority is set to "HIGHEST". In LibreOffice 24.8.3, the Skia "flush to native window" timer is still set to "POST_PAINT" which is a much lower priority than in the nightly build. So, I will try to see if setting the Skia flush timer priority between "HIGHEST" and "POST_PAINT" will fix this bug without causing tdf#163734 to reoccur. -- You are receiving this mail because: You are the assignee for the bug.
