I had basically the same problem years ago after install Wheezy (32-bit)
-- the current Stable then -- with the Gnome GUI on an Asus Eeepc 901
netbook.  To make a long story short, I discovered a conflict between
the Power Saving software and the Gnome Screensaver.  So, I disabled
the screensaver.  Never had the problem again. Later, I made sure the
screensaver didn't load at all.  Really, you don't need it, if your
power saving is set to turn off screen.

Also, since Buster is still an Alpha, expect more glitches.
