I have a Dell Optiplex 790, with graphics done on the processor chip (I think this is called Intel Graphics). Sometimes parts of my screen display are garbled; it is usually a problem with display of icons. I think the problem is in the linux kernel handling of graphics acceleration. I will attach some screenshots showing the problem. My system runs Ubuntu 19.10 and is up-to-date with patches.
