I too keep hitting this bug on a Gigabit NUC i3, 4GB RAM and also on a Fujitsu laptop i3, 4GB, both with xubuntu 20.04, when editing perl files of about 500 lines. The files can be on local storage or a NAS. I did think it was misbehaving with pastes (^V) but yesterday I had this:

Load Chrome and do a google search. geany autobackup.pl I ONLY selected a position in the file, deleted 4 characters and then saved ^s and quit ^q. The perl compiler then glitched because there were 4 or 5 copies of the google search text sprinkled throughout the code. I think this exonerates the paste operation and I think hardware too. I have tried to see whether the load or the save is the culprit but unfortunately, reproducing the fault is difficult. Here is some diagnostic infofrom the laptop but if more is needed please ask.
