But if I run xinit/startx, the performance is good.

Removing the printf from UNIMPLEMENTED() in there (so the printf) fixes the issue. In my case everyting is working but xv extension Considering xrandr I have small artefacts when using multiple screen, but s= till usable if I activate sna, it is totally broken if I use newer xorg along with newer xf86-video-intel from ports-graphics r= epo - with uxa: works but full of artefacts everywhere, unusable - with sna: instant panic concerning vt: - it is always slow and not related to the debug option being on by default= in the driver - multiple screens do work - when using a secondary screen (DP in my case) the secondary screen is fas= ter that the main screen Thanks for the work, that said with current xorg and current xf86-video-int= el using uxa it is perfectly usable, thanks a lot!
