I’ve been using SublimeText in various Ubuntu LTS versions upto 24.04 and I still have the same ‘bug’.
Whenever I already have some text/code copied into the clipboard and then (accidentally) press another CTRL-C but with no text or code selected, Ubuntu’s clipboard will be emptied.
Technically perhaps correct (because nothing was selected), but practically not the desired outcome. IMHO, the clipboard should not be cleared when copying a non-selection.
