I did notice that bug and it looked similar, but I've not seen any of 
the other corruption issues mentioned.

I should have noted that the fonts don't start out looking that way. The 
blocks only appear after I've clicked on one of the drop-down selection 
menus. That's probably and important detail. However, it's very 
intermittent. Happens about 60% of the time I think.

The other system I put my drive into had a Nvidia GTX 970 and definitely 
nouveau as it's newly installed Debian as of last week and I made no 
special configuration changes.
