Under debian buster, i updated and upgraded last week, meanothers TDE.
As from then, everything related with Xwindows has become extremely slow.
Before that, as from tdm to everything within the TDE display/desktop screen/environment worked perfectly.
video is AT RV370 X300 / X300SE
My experience with X300 is it's marginally useful with screens larger than 1680x1050. I notice considerable difference between 1680x1050 and 1920x1200. On Buster, speed doesn't seem to be any issue, but screen tearing is, at least, it is on a 1920x1200 screen.
Last I checked, there were many old ATI cards newer and with more RAM than an X300 in the $20 & under price class. It might be a good move for you to take if possible.
Normally I don't use an X300, but for purposes of this thread, I pulled an HD8570 temporarily in order to see how an X300 would work in Buster/TDE.
