Also, dragging two tabs together in Panorama causes the tab group outline to become corrupted, but only for a moment. D2D is enabled and layers.accelerate-all is true. New tab example: http://i53.tinypic.com/v5fq09.jpg Panorama example: http://i54.tinypic.com/intohl.jpg Reproducible: Always

This also happens without D2D (i see this on WinXP), accelerated Layers turned on is sufficient.

That's the same basic thing I reported in Bug 593600. I've attached videos, showing the problem, to that bug.

There's been a few times before where this doesn't occur, so I'm not sure about it always happening.

Can people seeing the garbled image issue go into about:support and copy their Graphics information from the bottom into this bug?

Seeing this. Windows XP SP3. Also the issues from Bug 593600. Here's the info from about:support : Graphics Adapter Description Radeon X1650 Series Vendor ID 1002 Device ID 71c1 Adapter RAM Unknown Adapter Drivers ati2dvag Driver Version 8.593.100.0 Driver Date 2-10-2010 Direct2D Enabled false DirectWrite Enabled false GPU Accelerated Layers Enabled 1/1 Direct3D 9

Could this issue I'm seeing in this thread be related to this bug report? See > http://forums.mozillazine.org/viewtopic.php?p=9865481#p9865481

Can people still reproduce this? We may have fixed it in another bug.

I haven't seen it for a while now, since those other graphics bugs got fixed.
