I’ve just upgraded 11.2 to 11.3, and immediately found that scrolling images in Firefox (eg Google) quickly freezes the whole system.
I found a matching bug:
[Bug 625023] New: Hard system freeze when loading image in Firefox
which was analyzed and closed as a duplicate of
Bug 597078 - intel[G33]/nouveau [mi] EQ overflowing. The server is probably stuck in an infinite loop.
I followed the advice of the bug owner in his last post which was simply:
“Updating to libdrm, Mesa, xorg-x11-server and xorg-x11-driver-video
of obs://X11: XOrg might be worth a try. Hope this update doesn’t
make your issues worse.”
(and with that, the bug was marked “resolved”.) So I added the X11: Xorg repository and upgraded libdrm, Mesa, xorg-11-server, xorg-x11-driver-video, and it did resolve the freeze.
However, the aforementioned scrolling in Firefox is still very poor quality (images blank out, don’t move smoothly, jumping, really slow, etc). The quality improves if I use a much lower monitor resolution, say 1024x768, but that’s inadequate.
My lspci output for the card is:

Is there anything I can do to improve Firefox image/scrolling now that I’ve already updated the X11 drivers? The same bug effect Deskop Effects, which I also wanted to start using.[/size][/size][/size][/size]
