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.
