I have reviewed my "about:support" contents and found preference "gfx.canvas.azure.backends" modified to "cairo" (from default "skia"). Toggling this entry between those two values (and restarting the browser) seems to fix/reproduce the issue 100% of the time.
I also had "gfx.content.azure.backends" set alike, but changing this does not seem to have any negative effect. So with both set to "skia" the issue seems solved for me. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1870161 Title: Tabs in Firefox 74.0 crash on some websites: [GFX1-]: DrawTargetCairo::Snapshot with bad surface To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/1870161/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
