GLX_INIT ERROR Failed to get GLX content on Raspberry Pi 4

I am getting an error when trying to run picom on my rpi4. Here is the error:

[neofax@RPI4-Manjaro ~]$ picom --experimental-backends

This is the same if I run just picom but works (w/o dual_kawase running xrender). glxinfo shows glx is working though.

I installed picom today on my rpi xfce image and I do not see what you are seeing. I installed fro a guide on the internet. I had to disable xfce’s internal compositor first before I ran the commands you listed above. Did you do that with your DE?

Are you using the picom-jonaburg git in the AUR or just picom? Normal picom works, but does not provide dual_kawase blur or animations. Also, this happens with glava from AUR. I think it may be due to the fact I am using two monitors as other websites/distros say to use a DRI=0:1 before running picom, but it does not work on my system.
