[Coordinated Graphics] Rendering glitches with
UseDamagingInformationForCompositing and semi-transparent background color
https://bugs.webkit.org/show_bug.cgi?id=305758
Reviewed by Carlos Garcia Campos.
If a non-opaque background color was specified and
UseDamagingInformationForCompositing feature was on, rendering glitches
occurred. It was reproducible with the following command:
> run-minibrowser --gtk
> --features=+PropagateDamagingInformation,+UseDamagingInformationForCompositing
> --bg-color "#00000050"
If a non-opaque background color is specified, the viewport is cleared before
setting a clipping rect. It should clear the viewport after setting a clipping
rect.
