Posting the output of
"inxi -br"
would be helpful.   Use the # button to mark up as code.  As always Ctl-Shift-C to copy from  a terminal.

Video driver  - i915   pretty basic, should be no problem.  unloaded, check. 
mine is i915 also Stable so my Mesa is older.

Your Package: libgl1-mesa-dev (19.1.6-1)    matches the Debian package page for Buster. 

1024 x 768 matches

Your repos are not way out, avant garde. 

Only thing I can suggest is to see that you have not  filled /   (your root)   "df" would show that.

Anybody else have any ideas??
