This could be also that the assumption made in 19e1101eb7c0f1f763e6f43a89db617584c18cc2 about driver handling invalid surfaces is incorrect. Can you revert that commit and see if issue is reproduced?

will try

not sure whats going on but with the reverted commit there is a new visual issue showing up on channel change with channels with lower resolution than the screen the first new frame is showing up unscaled an the zoomed to the screen size.

if I comment out both lines it make no visible difference here

another part from the syslog shows large negative values for duping frame
