For this update log window, I would like to have a darker header than the rest of the window but the window is rounded so the header glitches. I tried ClipDescendents but it only does it for the perimeter, and if I use UICorner it rounds both sides.
I dont understand, do you want the top part to be sharp? If so, you could try placing the darker header as a “sibling” of “UpdateLog” and give it a separate UIStroke.
oh, then you could simply apply the UI corner to the dark header as well, and duplicate it without the corner and make it smaller so that it covers the “round” bottom part
