Created attachment 24403 [details] screenshot illustrating the artifact When using UXA I see artifacts on that page when zooming: http://linux.wareseeker.com/download/java-tetris-1.0.rar/336355 the same page renders fine on xorg-server-1.3 + intel-2.2.1 with XAA. I was using FireFox-3.1beta3 on fedora rawhide (xorg-1.6 / linux-2.6.29 / intel-2.6.99), on a i945GM. Howto reproduce: 1. Go to the webpage: http://linux.wareseeker.com/download/java-tetris-1.0.rar/336355 2. Press <Ctrl> + <+>, to zoom one step 3. Scroll down a bit The gradient image on the left and right are black, as shown in the screenshot attached.
also happens on http://heise.de when zooming. Performance also drops a lot. Without zooming scrolling is smooth and responsive, but as soon as zoom is activated its slow and stutters.
The performance drop sounds like hitting the fallback code for scaling, which has been implemented in the hardware for quite some time now. Similarly it is also indicative that the black regions are unflushed pixmaps. Clemens, I think I've fixed several of the remaining i945 flushing bugs and coupled with the RenderPictureTransformation and PutImage acceleration now enabled in the driver, I believe this bug to be fixed - unreproducible at least. Please reopen if you can indeed reproduce this with the current drivers - I certainly couldn't following your steps. Thanks.
I can't reproduce it anymore with 2.9.1 - thanks for fixing this :)
