+Subject: Crash GPU process and clear shader cache when skia reports
+ compileError.
+
+Sometimes Skia failed to compile the cached GLSL because the driver had
+been changed but GL_RENDERER was still the same. In this case, we better
+crash the GPU process and signal the browser to clear the cache & let
+Skia regenerate the GLSL in the next run.
+
+Even if the compile failure wasn't caused by the cached GLSL. It's still
+better to crash the GPU process and let the shaders be re-generated.
+Because a failed compilation would have resulted in wrong rendering
+even if we had allowed the process to continue its execution.
+
