+++ 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.

    After adding AccelMethod "uxa" it works fine.

    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:
