In response to the frequent crashes from 1091903, I tried disabling D2D 1.1. Disabling it via the use1_1 pref fixes the crashes but then the browser's rendering periodically breaks, with all my windows becoming blank white. That state never recovers so I have to terminate firefox. Disabling it by removing d2d 1.1 from the backends list(s) causes various bitmaps in the UI to stop rendering; this is consistent across browser restarts and machine reboots. This reproduces on a clean profile.

We should probably disable this on Aurora.

Seems that disabling it is causing some issues as well?

(In reply to Milan Sreckovic [:milan] from comment #2) > Seems that disabling it is causing some issues as well? Fixing that should be a high priority. We don't want to repeat what happened with OMTC.

For reference, I'm also seeing some rather strange rendering artifacts on my primary desktop since D2D 1.1 landed. I'm going to force it off and see if things are okay there.

Removing d2d 1.1 from the backends list on my desktop (with gtx 670) produces the same missing bitmaps in chrome & content that I see on my laptop. So I don't think that's a driver issue.

You need to disable both USE1_1 and remove direct2d1.1 from the backend lists. Let me know if that works better.

That fixes the missing bitmaps on both my machines, thanks.

[Tracking Requested - why for this release]: D2D 1.1 is still active on 35, and rendering issues are something we need to be careful with right now.

Tracking (for what Kairo said).

(In reply to Sylvestre Ledru [:sylvestre] from comment #9) > Tracking (for what Kairo said). Well, we have since disabled D2D 1.1 on Aurora, so it's unaffected now. Or rather, the bugs are disabled. ;-)

OK! thanks for the info!

Milan, do you know what is the plan with D2D for 36? Thanks

(In reply to Sylvestre Ledru [:sylvestre] from comment #12) > Milan, do you know what is the plan with D2D for 36? Thanks I'll let Bas answer.

(In reply to Sylvestre Ledru [:sylvestre] from comment #12) > Milan, do you know what is the plan with D2D for 36? Thanks My hope is it can stay on. I believe there's still one or 2 issues which might still need to be fixed though. As far as I know however, most of the glitches should be gone and fixed.

Bug 1091903 is fixed now. In addition to that this bug was really more about wrongly disabling D2D 1.1 than anything else.
