--- Comment #10 from Ildar Nurislamov <absorbb at gmail.com> ---
As i see you've made the commit to your kernel branch to fix this.
I will wait for a fix in mainline kernel. Not sure about compiling 2.6 kernel
for OpenSuse 13.1.
Weird though if this caused by page flipping issues why only Qt application
affected (kwrite, okular appeared to be affected too, when dolphin is fine)
Mozilla Firefox never hangs and scrolls very fast even in fullscreen mode on
text and images heavy pages. even Java draws Netbeans fast. Maybe that is the
reason why QT uses raster backend by default.
