file needed to reproduce bug
Start vkquake, go into the options and change video settings to native
resolution and fullscreen, if not already the case.
Then quit the game, make sure TearFree is enabled and then start the game
again.
Then turn the game's vsync feature on, apply the change, turn it off again and
also apply this change.
-> TearFree is now disabled or broken (tears quite badly), also after closing
the game.
Get vkquake here:
https://github.com/Novum/vkQuake
You need to put the "id1" folder from the game's shareware version into your
home folder, which can be legally obtained from here (see also description at
the GitHub repo):

Since this link is usually or always not reachable, I'll attach the file to
this ticket as encrypted archive (password: "tearfree") and will delete it
later, just in case.
Tested with latest
