get current driver info:
sudo lshw -c video
current driver:
configuration: driver=amdgpu latency=0
replace AMDs driver with MESA:

So folloing the advice in the above link i first purged and removed then did
sudo lshw -c video
and it's still using the same driver, so i don't think it's actually using the mesa driver at all
after re-adding the packages it still shows the driver as:
amdgpu
seems the right driver is installed you can check with:
glxinfo | grep "OpenGL version"
says mesa there
The mesa drivers are better but I am still getting graphical problems.
