STR: 1. Open a new Fx profile (if it matters, I'm in a win7 VM under VMWare...) 2. Make the window horizontally smaller 3. Make the window horizontally bigger again ER: Correct cutout for window controls AR: Cutout for window controls spans entire range that the buttons have been in while resizing the window Matt, I'm guessing this is caused by your patch(es) from bug 940455. Any idea how/why, or should this be backed out?

This reproduces on a 'normal' desktop machine as well.

Forgot that this function can recurse.

Comment on attachment 8387193 [details] [diff] [review] fix-region-to-clear v2 This is still no good. With this patch, when Fx starts up, at first there's a rectangular fog over the window buttons, but then after a second or so, the fog covers them over again.

That patch does fix a "tab cut off" drawing glitch for me on Windows 8, FWIW.

Making this a bit more findable...

This should be fixed by the backout of bug 940455.

I can't reproduce this :( What OS version and about:support graphics settings do you have? It seems just fine for me, except the cleared out area lags behind a bit while resizing. I assume this was always the case though, since I can't see how my changes would affect that. Thanks for backing the other patch out though.

Comment on attachment 8387193 [details] [diff] [review] fix-region-to-clear v2 Reversing my original feedback, because I retested this, and it looks fine. I have no idea why it wasn't working for me on Friday. Work-week exhaustion, maybe. :/
