i3gaps, compton, screen glitching/tearing

Hello guys!

I`ve got a problem with my i3gaps + compton. Whenever I open more than 2 windows (terminal, browser etc.) screen is glitching. For example, i open two empty terminal windows and one with vtop and behind empty terminal window, i see some vtop glitched window. I tried to use different compositor(xcompmgr) and it was all the same. Does anyone can help me with this? Thanks!

Try disabling Compton to rule out compositor

Re: i3gaps, compton, screen glitching/tearing

Also FWIW since the intel DDX is in flux and often considered to be obsoleted by the modesetting driver, what happens if you remove your xorg configs (which reference the intel driver directly) and xf86-video-intel and let the xorg internal modesetting driver do it's thing?

Also: what kind of terminal (assuming it's a significant variable?), "xwininfo" and "xprop" of the terminal and maybe a screenshot.

Re: i3gaps, compton, screen glitching/tearing

Hello. I had the same issue with an IBM T60 with Intel Graphics card. When I disabled compton, all this flickering stopped. As a temporary solution, I downgraded compton from version 3.0.2 to version 2.0.2. This fixed the issue.

Re: i3gaps, compton, screen glitching/tearing

@V1del Thanks for your suggestion. I had a tearing problem with i3wm w/ and w/o compton. Removing the xf86-video-intel and enabling early KMS seem to significantly improve the situation whether compton is running or not.

Re: i3gaps, compton, screen glitching/tearing

Cirrus - i desibled compton and it glitches also.
V1del - when i remove intel drivers and xorg config my computer boots, but it doesnt load login screen, so i have to switch to command line(ctrl+alt+f2) and install my drivers again - what am I doing wrong?
Seth - Thats the output of xprop command - https://pastebin.pl/view/7276dbed - I use termite terminal but it also glitches with firefox etc.
MidnightRanger - when I disabled compton it also glitches, so i dont think it will help
Aurelieng - i tried this, but i did something wrong, because when i rebooted my computer, login screen(lxdm) couldnt load without intel drivers
This is link to screenshots where i captured tearing examples.

Intel driver removed, have you checked /var/log/Xorg.0.log for errors?

I don't see any errors in this one, it looks like it's the one generated with the Intel driver installed?

Re: i3gaps, compton, screen glitching/tearing

There's no xwininfo output, but I assume termite is an ARGB window?

[    62.313] (**) |   |-->Device "Intel Graphics"

You probably have some explicit reference to the intel driver in /etc/X11/xorg.conf.d or /usr/share/X11/xorg.conf.d

Re: i3gaps, compton, screen glitching/tearing

There is xwininfo output:
https://pastebin.com/CSmRwmZ3

And i have a file (20-intel.conf) in /etc/X11/xorg.conf.d (according to the arch wiki)

Here is xorg logs again, because I uploaded wrong file, sorry!
https://pastebin.com/dFx8hUtd

It looks like, it`s still trying to load intel drivers or something like this, why?

Re: i3gaps, compton, screen glitching/tearing

Ok, my mistake. I had this file 20-intel.conf and i didint remove this, i just changed name to 20-intelback.conf
So now my computer boots without intel drivers, and its better, but glitches sometimes happen. For example when i resize windows or something.
There are new Xorg logs, when it booted properly, sorry for mess:

Re: i3gaps, compton, screen glitching/tearing

Yup, is ARGB and your X server now uses the modesetting driver.
Ftr, you can just click the edit link in the lower right corner to mend your posts.

Does this also happen w/ xterm instead of termite?
