Steps of reproduction

In my case,

pacman -U /var/cache/pacman/pkg/picom-8-3-x86_64.pkg.tar.zst
restart X and i3wm

Run termite with the following config

[colors]
foreground = #000000
background = rgba(255, 255, 255, 0.85)

Expected behavior

Termite window is translucent, some of the desktop background is visible.

Current Behavior

Termite window is fully opaque. Additionally, I get persistent screen tearing when scrolling or watching videos in a browser.

Remarks

Reverting to 7.5-3 (arch suffix) fully solves the issues.

duplicate of https://github.com/yshui/picom/issues/460? though this bug has more info.

sandsmark commented 4 years ago

FWIW, I don't get the tearing and I get transparency (I use a custom config), but I seem to have some performance regressions when I turn on background transparency in Konsole with picom running.

andrei-dubovik commented 4 years ago

@sandsmark Could you share your config file? I'll try running v8 with your config. Albeit, I've scanned through the settings and there does not seem to be anything obvious that would cause my issue.

absolutelynothelix commented 4 years ago

can't reproduce your opacity issue with the config file you provided and termite (though i'm using bspwm).

Delhi-Babu commented 4 years ago

duplicate of #460? though this bug has more info.

my windows are transparent and as in video #460 once I erase (move a window over the black area it gets erased) after that I didn't get those flickering and tearing anywhere (I am not a heavy user)

https://github.com/sandsmark/dotfiles/blob/master/picom.conf Thanks. I've tried it, but I still get the same issues: no transparency and tearing.

absolutelynothelix commented 4 years ago

wait, there is something wrong. the diagnostics output you provided has a lot of messages about deprecated options, but the configuration file you provided doesn't have these options. looks like picom uses some other configuration file than you provided.

also, take a look at the diagnostics output:

[ 09/08/20 10:37:08.426 parse_config_libconfig ERROR ] "paint-on-overlay" has been removed as an option, and the feature is enabled whenever possible
[ 09/08/20 10:37:08.426 main FATAL ERROR ] Failed to create new session.

picom won't start because the configuration file used contains a deprecated options that triggers an error for some reason, so of course there is no transparency and there is tearing because picom isn't running.

yshui commented 4 years ago

@andrei-dubovik picom didn't start because you have an outdated config file.

Reading the log is a good first step to triage a problem yourself. I do try to make the log messages as useful as possible.

andrei-dubovik commented 4 years ago

Indeed, an old configuration file was in use, which prevented picom from starting. My bad for not spotting it myself. Thank you for your help.
