Closed Bug 1025914 Opened 6 years ago Closed 6 years ago
Incomplete repaint when scrolling up on theverge
STR: 1. Go to http://www.theverge.com/ . 2. Scroll down until the boxes with the colorful gradients at the top are no longer visible. 3. Slowly scroll back up. Notice that the colorful boxes are no longer all that colorful because the box shadows haven't been repainted properly. This was probably caused by bug 1008301 but I haven't confirmed it yet.
The previous testcase had stopped showing the bug due to bug 1024148.

This happens because the scrolled layer doesn't paint the newly-scrolled-into-view parts of the green box while those parts are covered by the blue bar. Before bug 1008301, the revealed parts of the green box would be painted once they were no longer covered by the blue bar (due to the "changed visible region" invalidation for the inactive opacity layer manager). I've tested a try build from bug 1022612 and it fixes this bug. I was planning to back out bug 1008301 on Aurora anyway, and I probably should back out it on mozilla-central as well, until bug 1022612 has landed and stuck.
Depends on: 1022612
I backed out bug 1008301 from Aurora so this bug is no longer present there.
Bug 1022612 has fixed this.
After the uplift to Aurora, bug 1022612 (which fixed this) was backed out there again, so I also backed out bug 1008301 (which caused this) from Aurora again.
System Windows 7 64 bits Pro I reproduce the bug with the nightly 33 version (2014-06-16): there's a box repainting bug with a staircase effect on the boxes bug fixed and verified on nightly 34 version (2014-08-27)
