My first  bug report because why not.
Slackware64 current, nfidia 780 3GB prop. driver 470, 4K LG  Gallery edition TV. 
Tried unsuccesfully to reproduce the bug.  Wanted to see more spreadsheet data  numbers on a big screen and sure after quick CONTROL mouse scroll more data came from the crash backtrace,

The reporter is unsure if this crash is reproducible.
