        <pre>On Fedora 22 with SNA I encountered the following rendering artifacts when used
emerald decorator:
<a href="https://bugzilla.redhat.com/attachment.cgi?id=1096086">https://bugzilla.redhat.com/attachment.cgi?id=1096086</a>

HW used:
graphics:  Card: Intel Haswell-ULT Integrated Graphics Controller
           Display Server: Fedora X.org 117.4 drivers: intel (unloaded:
fbdev,vesa)
           Resolution: <a href="mailto:1366x768@60.00hz">1366x768@60.00hz</a>
           GLX Renderer: Mesa DRI Intel Haswell Mobile
           GLX Version: 3.0 Mesa 10.6.9 (git-8957b69)

It seems the problem was caused by the following commit:
<a href="http://cgit.freedesktop.org/xorg/driver/xf86-video-intel/commit/?id=ef24cb1b223486d7dfe57f33c28d8692f9857c98">http://cgit.freedesktop.org/xorg/driver/xf86-video-intel/commit/?id=ef24cb1b223486d7dfe57f33c28d8692f9857c98</a>

It works correctly in UXA. It works in SNA if I use git snapshot before the
above mentioned commit or even with the latest git head with the reverted above
mentioned commit.

It also works correctly with different drivers (e.g. nvidia).

I think it should work the same in UXA/SNA, thus filling this bug.
