Might be a problem with AMD video cards.

I've had OMTC on for several weeks now and running an older AMD video-chip on an Athlon II Phenom, not seen any glitches in graphics here.

Jim, your also running an old driver. If you remember the last AMD related problem I think that started with the 2012 drivers.

FYI, Scrolling this page produces blank portions and now my scroll bar becomes black at the top.

I'm able to get the black scrolling bar pretty often with OMTC enabled. When I disable it no more black scroll bar. Running in safe mode which turns off HWA as well as OMTC also produces no black scroll bars.

I get the same problem, HD7750, catalyst 14.1 and windows 8.1

Might be another problem with HD7xxx AMD cards. Possibly with the newer cards also which other than the 290 are just rebranded 7xxx cards.

I get the same problem, HD 7850, latest calatyst win 8.1 x64

Strangely, since a few nightlies I get the opposite behavior : I see black flashes and loading animation corruption on GPU accelerated windows, unless I enable OMTC. GPU accelerated windows use D3D11 with OMTC, D3D10 without. GTX580, Win 7 x64

Something seems to have fixed my video glitches. I run with Inbound and when I enabled OMTC earlier in the day I had the glitches. Later on I applied a newer cset and no more problems.

Is this related with bug 978282? If so, this isn't fixed - but bug 975824 isn't marked fixed as well.

I don't think they are related. I have several UNIX systems and only encounter bug 978282 on the one with Intel Sandybridge graphics, which is also what the reporter of that bug has.

Although the steps I was using to do my bisect did not produce a failure on AMD/ATI graphics, Facebook ends up with black all over the place on my AMD/ATI graphics system. Backing out bug 974709 fixed both issues.

The pending patch on Bug 977963 should avoid this issue.

Do you still reproduce this ?

There is one glitch that I get on occasion. Toolbars, Nav bar, tabs, will sometimes change to the color of my caption bar that is set in Windows 8. Changing between normal and maximize mode corrects it.

Are you sure it's OMTC specific?
