+Subject: [PATCH 21/50] egl/wayland: post maximum damage when blitting
+
+When blitting, as part of the "is_different_gpu" case when swapping
+buffers, the blit is done using the full surface dimensions, ignoring
+the damage region. This results in corruption of the non damaged region
+on screen. Workaround this by posting maximum damage when blitting.
+
+A better fix would be to limit the blit to the damaged region, at least
+when the number of damage rectangles is 1.
