      I'm trying to debug my extension that crashes Opera during a long-running process. So I start Opera with verbose logging enabled (opera --enable-logging --v=1 &).

      The crash doesn't happen because Opera is stuck in an endless loop displaying this "error" hundreds of times per second:

      ERROR:paint_controller.cc(548)] PaintController::FinishCycle() completed
      

      I searched in about:flags, but did not find a way to disable the PaintController.

        Try disabling opera's hardware acceleration and see if it helps.

          Thanks. Although that didn't get rid of the PaintController errors, it stopped the looping, which made the log manageable.

          The log is quite cryptic, but it looks like the crash happens here:
