i have a fun one. i like to write and use firefox for research. i am using kde neon and past 3 weeks, on 7.2.5 and earlier, i think from 7.2.2 every often if i Alt-tab out of libreoffice, the app would crash. thankfully i have a habit of automatic ctrl-s whenever i take a break after finishing a sentence so i never lost any data but it was fun to have the same bug for quite some time.

no problems with 7.3 so far
