Created attachment 147296 [details] SVN diff of affected ports Shift key is not released if X11 group switch is something other than Control-Shift. This affects, in particular, games/flightgear. I took the patch from here: https://www.mail-archive.com/debian-bugs-dist@lists.debian.org/msg1218650.html
Auto-assigned to maintainer amdmi3@FreeBSD.org
Could you elaborate on how this bug can be reproduced?
Run: $ setxkbmap us,ru -option "grp:shifts_toggle" Launch FlightGear and use some keyboard shortcut containing "Shift". Once on, the modifier will remain so until the game is restarted. People using "Control-Shift" to change keyboard layout are not affected.
