DoFlicky installed proprietary driver for my legacy nVidia card, but something is weird. On non-white display, I get messed pixels on my screen. There's a screenshot where it's clear what I say. 
Any idea how can I fix it? Don't want to use Nouveau driver, because I play some games on my Solus. And BTW, it's not Solus problem I know, I get those messed pixels on other distros with proprietary drivers. My GPU is nVidia Geforce 9500 GT (quite old, already unsupported by nVidia 😐)
