Elad HenOnce upon a time, a long long time ago, there was xorg.
Xorg had this bug: instead of switching keyboard layout when the key combination is released, thus allowing the layout switching combination to be used as part of other key combinations, xorg switched layouts upon key press.
This meant that, for example, it your layout switching was done with alt+shift you couldn't use alt+shift+tab to flip backwards between open windows.
Xorg being xorg, although the bug is open since 2004 it hasn't been patched. However, #Ubuntu came along and thought that maybe linux should be usable, and implemented the patch that already existed. And all was well between 12.04 to 17.10. In 17.10 the patch made some problems. This coincided with Ubuntu stopping giving a damn about users and moving to GNOME "break user experience and don't look back". So instead of fixing the patch they stopped using it.
The patch was fixed by its maintainer (an Arch user...) but #Ubuntu stopped using it. Along came Ubuntu 18.04 and after a while #linuxMint 19 based on it, carrying this regression like a xenomorph in its abdomen (sorry. Getting carried away here).
Now all I'm asking is how many years before a regression that hinders usability and has an easy patch will again be fixed for simple users, for whom hunting after patches in xorg bugzilla isn't accessible?
