Description mail-redhat 2015-08-03 20:31:26 UTC
+++ This bug was initially created as a clone of Bug #1226531 +++

Issue description: The screen refresh takes so long, it's visible, so e.g. while scrolling a webpage you see a wave-like pattern while it's refreshing.

After I updated the the Intel driver to 2.99.917 12.20150615.fc22 in the upgrade process from fc22.

Workaround:
    After adding AccelMethod "uxa" it works fine.

Constraint:
    It only occurs while running on X, it's fine on Wayland. Wayland has other issues like the context menu is popping up at a fixed place on the left top of the screen (not 0,0) so it's no fallback option.

From lspci:
    00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09)
