Summary [WPE] REGRESSION(r253675) Crash when using threaded rendering
Miguel Gomez
Reported 2020-05-27 05:06:21 PDT
r253675 modified ImageBufferCairo::draw and ImageBufferCairo::drawPattern (currently ImageBufferCairoBackend::draw and ImageBufferCairoBackend::drawPattern) to use cairo and the platformContext to paint instead of using the GraphicsContext methods. While this is ok is most of the cases, when using threaded rendering, all the drawing must happen through the GraphicsContext so the rendering commands can be recorded and replayed afterwards. Even more, the GraphicsContextImpl used in this case is a CairoOperationRecorder, which doesn't even have a platformContext. So this ends crashing.
