I get graphics corruption when using the QupZilla web browser and the
xf86-video-intel driver in SNA mode. All I have to do is start QupZilla: the
problem happens immediately at startup, and it remains until I close QupZilla.
UXA mode is fine instead. My GNU/Linux distribution is Gentoo. My motherboard
is an Intel Desktop Board DQ35JO from year 2009. I suspect the problem is not
really with QupZilla but with QtWebEngine. Other applications work fine.
