Bug ID: 521726
Summary: Dead keys (circumflex, diaeresis) broken in
LibreOffice after kwin upgrade to 6.7.0
Classification: Plasma
Product: kwin
Version First unspecified
Reported In:
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: wayland-generic
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
Description:
Since the upgrade of kwin from 6.6.5 to 6.7.0 (2026-06-17), dead keys no longer
work in LibreOffice under a KDE Plasma Wayland session. Pressing a dead key
(e.g. ^ or ¨) has no visible effect; the accented character is never composed.
Pressing the dead key twice correctly outputs the bare accent character,
confirming that the key is recognized as a dead key but the composition step
fails.
This regression is isolated to LibreOffice. Firefox and Thunderbird, both GTK
applications running in the same session, handle dead keys correctly.
Environment:
OS: Fedora 44
KDE Plasma: 6.7.0
kwin: 6.7.0
LibreOffice: 26.2.4.2 (VCL backend: kf6)
Session type: Wayland
Input method: none (XMODIFIERS=@im=none)
Keyboard layout: French (fr)
Steps to reproduce:
Run a KDE Plasma Wayland session on Fedora 44 with kwin 6.7.0
Open LibreOffice Writer
Press the ^ dead key followed by e
Expected result: ê is inserted
Actual result: nothing is inserted on the first keypress; ^ appears only on a
second keypress of the same key
Workaround:
Forcing LibreOffice to use the GTK3 VCL backend resolves the issue:
SAL_USE_VCLPLUGIN=gtk3 libreoffice
This confirms the regression is specific to the interaction between kwin 6.7.0
and LibreOffice's default kf6 VCL backend under Wayland.
Bisection:
kwin 6.6.5 (prior to 2026-06-17): dead keys worked correctly in LibreOffice
kwin 6.7.0 (from 2026-06-17): dead keys broken in LibreOffice
