I3blocks with transparent icons

Hi everyone! I’m with an issue with i3blocks. My icons (discord / telegram) are transparent on the bar.

I’m using compton/picom and here is my picom.conf:

# GLX backend: GLX buffer swap method we assume.
# Could be undefined (0), copy (1), exchange (2), 3-6, or buffer-age (-1).
# undefined is the slowest and the safest, and the default value.
# copy is fastest, but may fail on some drivers,
# 2-6 are gradually slower but safer (6 is still faster than 0).
# Usually, double buffer means 2, triple buffer means 3.
# buffer-age means auto-detect using GLX_EXT_buffer_age, supported by some drivers.
# Useless with --glx-use-copysubbuffermesa.
# Partially breaks --resize-damage.
# Defaults to undefined.

I really need some help. Thank you guys!

Try to switch this back to defaults 0.75 or off to 0 and see if it changes.

Shift+Mod+r

You have a lot of eight-character hex colors, which implies transparency. Maybe try and remove the ‘CC’ endings (one by one) and see if the icons turn opaque?

I tried these changes and still have the same issue

Two more things that come to my mind. Note I am relatively an i3 wm noob.

Perhaps you could add this app to the list to exclude shadow. The other thing, in your config file, is the line that mentions compton or picom exec uncommented? Just making sure your config file pics up your picom setting.

I just tried this and still not success :frowning_face:
In my .i3/config there is a line with:
exec_always --no-startup-id picom

Sorry to hear that. I installed manjaro i3 community on my other laptop yesterday evening. Will see if I run into similar problems. Did you modify the standard config files that comes with the install?

One thing that helped me with some transparency/shadow issue with zoom and screensharing was to change the option of the following line in the i3 config file

   exec --no-startup-id picom -C

where option -C: Disable shadow effects on panels and docks

Maybe worth another shot, sorry that I can’t be of more help.
