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.
