When switching from Pixman 0.11.8 to 0.11.10, KDM 4.1.1 started to misrender some artwork. I'm attaching screenshots
Created attachment 18734 [details] correct rendering sorry, couldn't get a screenshot when kdm is running, I had to use a camera
Created attachment 18735 [details] incorrect rendering same code, running with pixman 0.11.10 the stripes are not wanted at all :)
We have a bugreport at archlinux.org: http://bugs.archlinux.org/task/11419 Screenshot: http://bugs.archlinux.org/task/11419?getfile=2490 Notice the artifacts in the translucent dragbox and the dotted patterns on top of the firefox tabs. The users reporting this issue on our distribution are using nvidia drivers, but there's also at least one of them using the xf86-video-nv driver.
I have the same problems on archlinux using the intel driver at 24bpp on a GM965 controller. Apart from the dotted lines almost everywhere, an other very visible effect is in gedit. The part after the print margin gets all blurred or fuzzy or full of vertical lines, depending on the size of the window.
Does the bug go away if pixman is compiled with --disable-sse2 passed to configure?
Actually never mind. I can reproduce it.
