Are you using xf86-video-Intel driver? Check on /etc/X11/xorg.conf.d/20-intel.conf If your acceleration is sna change it to uxa See if that helps. I know I had to change as lots of issues with display when it was upgraded. On 08/11/2015 12:16 PM, Lucas Prado Melo wrote:

Hello,

I've been experiencing some visual glitches in Gnome or Xorg (I guess?). I can't really describe exactly what is happening but here are some examples of weird behaviors:

1) Sometimes, when I change tabs in my web browser (Google Chrome), a region from the previous web page gets stuck and I need to change tabs a number of times to return to normal behavior.

2) In Chrome, sometimes, when I exit full screen, several visual glitches happen and I must also change tabs.

3) In the game Klotski, when I repeatedly click on the pieces, small details change.

Do you have any suggestions that might help me fix this?

You're welcome. I believe it is a reported bug. On 08/11/2015 12:51 PM, Lucas Prado Melo wrote:

It seems to be working fine, thanks. :-)

I saw that, but as I said in the 1st reply, this only occurred after the upgrade of xf86-video-intel, so I feel it is a regression and I can't recall where I saw it as being reported as a bug. On 08/11/2015 03:20 PM, Karol Blazewicz wrote:

You're welcome. I believe it is a reported bug. Please bottom-post. There's https://wiki.archlinux.org/index.php/Intel_graphics#SNA_issues but it's pretty vague, so you can miss it.
