Debian is unusable with Radeon any form of gpu acceleration

The problem is between Radeon glamor DRI3, composers vsynch/  xrender glx

no browser works  instant crash any tab firefox , epiphany invisible websites
but preview brackets show a foto

dri3 glamor does not launch libreoffice

ANY DRI or DRIVER: menu software quits after clicking one of the bottom choices
extensions etc


all runs only because itis lightdm xfce
in wayland and gdm3 it would freeze
before login

*************
a simple mismatch of desktop renderer with obsolete drivers ?

all maybe simpler to fix if itis a   set of

mismatching actuality

allthebest!

I believe bug belongs against the xserver-xorg-video-radeon package.
[It's definitely not a bug in bugs.debian.org]

You should also provide the Xorg.0.log and any kernel logs which show
the behavior that you are seeing (whatever is actually happening).
