--- Comment #8 from bastimeyer...@gmail.com --- Created attachment 170878 --> https://bugs.kde.org/attachment.cgi?id=170878&action=edit xmodmap -pke I found the cause of this. As hinted, I've set up two different keyboard layouts, "en_US International with dead keys" and the regular "en_US" one. In the "Keyboard -> Key Bindings" settings menu, I have "Both Shifts together" set in the "Switching to another layout" category. When disabling this double-shift-press behavior, the issue does not occur. With the option, pressing shift results in: Scan code: 42 Xkb symbol: 65034 With the option, releasing shift results in: Scan code: 42 Xkb symbol: 65505 Without the option, pressing shift results in: Scan code: 42 Xkb symbol: 65505 Without the option, releasing shift results in: Scan code: 42 Xkb symbol: 65505 -- You are receiving this mail because: You are watching all bug changes.
