Crash in Sk
This bug was filed from the Socorro interface and is report bp-8d7a0fc0-0fcc-4449-b2a0-eb9350180720. ============================================================= Top 10 frames of crashing thread: 0 libxul.so SkCanvas::setMatrix 1 libxul.so mozilla::gfx::DrawTargetSkia::SetTransform gfx/2d/DrawTargetSkia.cpp:2030 2 libxul.so mozilla::gfx::SetTransformCommand::ExecuteOnDT const gfx/2d/DrawCommands.h:1012 3 libxul.so mozilla::gfx::DrawTargetCaptureImpl::ReplayToDrawTarget gfx/2d/DrawTargetCapture.cpp:351 4 libxul.so mozilla::gfx::DrawTarget::DrawCapturedDT gfx/2d/DrawTarget.cpp:187 5 libxul.so mozilla::layers::CapturedTiledPaintState::Paint gfx/layers/PaintThread.cpp:126 6 libxul.so mozilla::layers::PaintThread::AsyncPaintTiledContents gfx/layers/PaintThread.cpp:457 7 libxul.so mozilla::detail::RunnableFunction<mozilla::layers::PaintThread::PaintTiledContents> >::Run gfx/layers/PaintThread.cpp:437 8 libxul.so nsThreadPool::Run 9 libxul.so nsThread::ProcessNextEvent ============================================================= There is 1 crash in nightly 63 with buildid 20180719220047. In analyzing the backtrace, the regression may have been introduced by patch  to fix bug 1471639.  https://hg.mozilla.org/mozilla-central/rev?node=299faea63d79
There is a "spike" of crashes with signature matching regex Sk[A-Z]+.* in nightly with buildid 20180718220144 so just after the patch for bug 1471639 landed (see crash-stats at https://bit.ly/2uQAnqW). buildid # of crashes ------- ------------ 20180720101508 5 20180719220047 7 20180719100142 4 20180718220144 4 20180606220131 1 20180606100133 1 20180602100108 1 20180601222241 1 20180518222751 1 20180517220057 6 20180514100123 1
Is it possible that bug 1471704 is at fault here? They landed very close to each other. Bug 1471639 shouldn't affect linux as it changes behavior for a pref that's not enabled there (not that I'll say never when it comes to crashes). Bug 1471704 changed us to use a thread pool for painting which I feel is more likely to cause random crashes. I'll still look through the crashes and see if I can figure anything out.

reverting affected status for 61 and 62 as per comment #1
I'm going to close this assuming that the crashes are resolved since bug 1471704 has been backed out. Please reopen this if the crashes continue.
