Frequently I see the chrome UI not painted correctly and/or context menus painted all black. Not sure how to repro. I'll attach screen shots next time it happens...

Could start with an assumption that it's related to the error messages. OptimizeSourceSurface and GetDataSurface don't always seem to succeed, but not all the callers appear ready for it. In particular, SourceSurfaceCairo::GetDataSurface doesn't seem to be checking if the cairo call succeeded?

Bas, why are we attempting to make a D2D texture with a dimension of 24914? Don't we have something in place that stops us before we get that deep into accelerated code path?

What should happen in this codepath (and from what I can tell would happen), is the D2D error will just cause us to 'not optimize' the DataSourceSurface. We should then attempt to draw directly with the DataSourceSurface and it -shouldn't- cause any problems. It's hard to say whether the error is actually related to the problem, DougT was going to put a breakpoint on the error to see where it's coming from. Most likely I suspect the drawing issues and this error may have a -common cause- rather than being directly causally related. If they're related at all. I wonder if Doug ever managed to get the stack trace.

Nothing under the debugger yet.

fwiw, i have not seen this in nightly.

(In reply to Doug Turner (:dougt) from comment #5) > fwiw, i have not seen this in nightly. I wonder if this was somehow related to partial presents.. maybe those will get disabled now on the SurfaceBook.

We have seen a number of these problems traced down to driver issues.

milan, other browsers don't seem to have this problem. Can't we work around driver issues?

(In reply to Doug Turner (:dougt) from comment #8) > milan, other browsers don't seem to have this problem. Can't we work around > driver issues? Right - based on some information from AMD (they were of huge help here), we have reasons to believe it's the higher than usual number of D3D devices in Firefox (we use one per video, and the usual total is 1) that's hitting a race condition (which AMD has fixed in their latest driver.) We don't have direct evidence that we're hitting the same problem with other vendors, but the problems look reasonably similar, so the current theory is that it is the same issue. Bug 1284672 is where we're trying to reduce the number of devices used.

It's been a couple months since AMD's driver was updated and it looks like bug 1284672 has been fixed since then. Can we get this retested to see if the situation is resolved or at least improved?
