--- Comment #42 from Adric Blake <promarbler14 at gmail.com> ---
The bug is significantly older than anticipated.
So far, I have been able to experimentally deduce that kernels all the way back
to Linux 4.11.9 have the bug. Kernels that I've tested so far that work
bug-free are linux-lts 4.9.67 and linux 4.10.9. I have yet to bisect further as
the compiler is being a pain and apparently needs to be downgraded. Will
update, eventually....
For note, my method of testing is opening previously said dwarf fortress game
(other games not tested) and both casually and aggressively switch workspaces
to and from the game window using marco, my window manager. It's guaranteed to
trip the bug in under 10 minutes (usually no more than 5).
