Unable to find compton settings that work perfectly

[Brett99]

Platform:
Arch Linux, running BSPWM

GPU, drivers, and screen setup:
Thinkpad T480, 1080p, no external monitor, integrated Intel graphics.
I've tried both xf86-video-intel and xf86-video-intel-git

Compton version: I've tried the official compton arch package, and compton-git.
Currently on git-v0.1_beta2-87-g316eac0-2017-04-30 with compton-git

Compton configuration: https://pastebin.com/raw/CkifKypn

Steps of reproduction

I've tried every suggested configuration I could find on the internet, but I haven't found a single one that works properly.

Here are some of the issues I've run into:

• text sometimes doesn't appear in urxvt until I manually force the window to refresh
• screentearing all the time
• screentearing only while playing fullscreen videos in chromium
• no screentearing, and then it mysteriously starts back up again
• terminal windows automatically unfocusing themselves when I type
• solid black terminal windows, no text
• screen blinking once every few seconds while using chromium
• white flashing when opening/closing things

Expected behavior

It should not do any of the things mentioned above.

Current Behavior & Other details

• I don't know how to reliably make it break urxvt, but I suspect it has something to do with xft. Perhaps mentioned in #152.

• I don't remember every configuration I've tried, because I've tried so many in the past few days. Let me know if I should test any specific ones. If I can't completely fix this, I might have to return my laptop and get one with an NVidia card.

• I was able to get rid of the urxvt issue by using the xrender backend, but could not get rid of the tearing with compton. The solutions in #376 did not fix the problem. I was able to get rid of the tearing by changing the config files for the Intel driver, but this would sporadically stop working, resulting in tearing again.

My compton.conf file has not changed. I've just been starting compton with different flags.

# this produces really bad screentearing
compton \
    --config ~/.config/compton/compton.conf \
    --backend xrender

# this does not fix it
compton \
    --config ~/.config/compton/compton.conf \
    --backend xrender \
    --xrender-sync \
    --xrender-sync-fence

# this produces really bad screentearing
compton \
    --config ~/.config/compton/compton.conf \
    --backend glx \

# this fixes some of the screentearing, but it's still really bad with chromium
compton \
    --config ~/.config/compton/compton.conf \
    --backend glx \
    --vsync {drm, opengl, opengl-oml, opengl-swc, opengl-mswc}

# this causes windows to quickly focus and unfocus
compton \
    --config ~/.config/compton/compton.conf \
    --backend xr_glx_hybrid \

[Brett99]

Enabling acceleration in Chromium seems to fix the tearing. I had turned it off because it's responsible for Chromium hanging for a few seconds sometimes. I guess I'll need to find another way to fix that.

I still don't have a way to prevent tearing without making urxvt lag.

What is your compton.conf?

[Brett99]

My compton.conf can be found in the original post.

Switching to the modesetting driver seemed to help, but I'm still getting tearing when playing fullscreen videos.

[smlx]

I've got a T430 with intel graphics. Here are the important settings from my compton.conf. Note that fullscreen video will tear if unredir-if-possible is set - that's why I exclude vlc.

# Try to detect fullscreen windows, and unredirect them.
unredir-if-possible = true;
unredir-if-possible-exclude = "name *?= 'vlc'";
# reduce flickering on unredir
paint-on-overlay = true;

# Use the 3D renderer
backend = "glx";
vsync = "opengl-swc";
# recommended performance improvements
glx-no-stencil = true;
glx-no-rebind-pixmap = true;

[deviantfero]

do you get random freezes here and there with this settings @smlx ?

[smlx]

No, I don't. However I'm on Debian, not Arch.

[ChrisLahaye]

@deviantfero try without paint-on-overlay on false

Try this: It works perfectly for me: https://github.com/jEsuSdA/the-perfect-desktop/blob/master/compton/compton.conf

Worked for me as well, thank you!

@jEsuSdA This URL returns 404, can you copy the contents of this file if you still have it? Thank you!

Edit: Maybe you still have it, @gnuy?

[meetnick]

I need that compton.conf file too! DO you still have it @gnuy ? the link give 404 not found
