Comment # 19 on bug 1099778 from Michal Srb

Since you also observe the issue only with certain keyboard, it really seems to
be hardware limitation. Unfortunately, we can not do anything about that.

You can try to use different key for switching the layouts, for example the Win
key: setxkbmap "us,cz(ucw)" -option grp:win_switch

Please reopen if the key combination worked in older version of openSUSE or
other operating system.
