Bug ID: 516598
Summary: After the update on 2026-02-23, keyboard layout
switching options labeled "(while pressed)" no longer
revert to the default layout upon key release.
Classification: Plasma
Product: kwin
Version First unspecified
Reported In:
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: input
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Target Milestone: ---
Steps to reproduce:
Go to System Settings > Keyboard > Layouts > Configure layout options.
Under "Switching to another layout," select "Caps Lock (while pressed)" or
"Left Alt (while pressed)."
Ensure two layouts are configured (e.g., US and Danish).
Press and hold the designated key.
Type a character, then release the key.
Observed Result: > The layout switches on the initial press but remains on the
secondary layout after the key is released. It only switches back if the key is
pressed a second time (behaving as a toggle).
Expected Result: > The layout should immediately revert to the primary layout
as soon as the key is released.
Additional Information: > This was working correctly prior to today's update.
Verified with multiple keys (Caps Lock and Left Alt), suggesting the issue is
with the "while pressed" state logic rather than a specific key mapping.
