Intel HD Graphics glitches (even with UXA enabled)

Hello,

I'm running Arch on my Asus N550JV-CN270H. It's running real nice, except for one thing: Occasionally I get glitches.
This laptop has two GPU's: an Intel HG Graphics 4600 and a GeForce GT750M. I do not have interest on using the Nvidia GPU. The monitor "directly connected" to the Intel GPU. So the Nvidia shouldn't have to do anything with this.

To give you an idea of the glitches I'm talking about, I recorded the following 3 videos: https://www.youtube.com/playlist?list=P … V9F7qn7LU9
The glitches seem to be pretty random. The laptop can be running for a few hours without a single graphical glitch. But the glitches can also occur just a few minutes after boot. Putting the laptop to sleep doesn't have any effect on the glitches.

I used to have Debian stable (Jessie) installed, but because many packages were older than I liked, I upgraded to Testing. This introduced the glitches for me. I did some Googleing and came that the conclusion had to be in SMA. So I added the "fix" to /etc/X11/xorg.conf.d/20-intel.conf. This didn't make a difference for me. Because I thought this was a Debian bug, I installed Arch. Arch still had the problem, so installed the Nvidia driver and Bumblebee. This didn't fix anything either. Adding the fix didn't do anything.

This is my /etc/X11/xorg.conf.d/20-intel.conf:

Section "Device"
  Identifier  "Intel Graphics"
  Driver      "intel"
  Option      "AccelMethod"  "uxa"
  #Option      "AccelMethod"  "sna"
EndSection

My /var/log/Xorg.0.log verifies that it's running in UXA mode:

[     3.042] (**) intel(0): Option "AccelMethod" "uxa"
[...]
[     3.073] (II) UXA(0): Driver registered support for the following operations:
[     3.073] (II)         solid
[     3.073] (II)         copy
[     3.073] (II)         composite (RENDER acceleration)
[     3.073] (II)         put_image
[     3.073] (II)         get_image

Installed driver: xf86-video-intel 1:2.99.917+478+gdf72bc5-3

At this point, I had Debian, Arch and Windows 10 installed. I removed Debian and Arch and reinstalled Arch. This time I didn't reinstall the Nvidia graphics driver, because I don't want to do anything with that GPU. I added /etc/X11/xorg.conf.d/20-intel.conf again. Still issues, obviously.

Everyone seems be able to solve all issues by switching to UXA. But it doesn't do it for me.

If you need more information, please ask. Can anyone help me with fixing these glitches? Thank you very much in advance. Also, if you see any grammar errors, feel free to point out. I'm still improving my English.

Re: Intel HD Graphics glitches (even with UXA enabled)

I have an HD4600 and this works:
https://wiki.archlinux.org/index.php/In … free_video

However, I prefer to use compton in my startup:

compton --backend glx --paint-on-overlay --vsync opengl-mswc &

Off topic: why isn't compton in the official repositories?

Switching to SNA en enabling tear-free video seems to have solved the glitches.
