every so often, screen just goes black

Same here on a notebook with Intel graphics.

I also noticed that up to F10, a frame rate of 50 Hz was offered and set 
for the notebook display. On F11, there is no 50 Hz setting, and the 
display is set to 65 Hz (if I remember correctly, I don't have the 
notebook here right now).

Maybe the frame rate slightly exceeds the upper limit of the display's 
specifications, and the display blanks for a short moment because of that?
