--- Comment #4 from Michael Peter <[email protected]> --- Further testing across different Mint setups shows this issue only occurs when LibreOffice runs with the GTK3 VCL backend inside a Plasma (KDE) session. Matrix of results: - Mint 21.3 Cinnamon (GTK3 3.24.33, X11) → OK - Mint 21.3 Plasma (GTK3 3.24.33, X11) → greyed header zones - Mint 22.2 Plasma (GTK3 3.24.41, X11) → greyed header zones - Mint 22.2 Plasma (KF5 Qt6 backend) → OK So it seems related to GTK3 + Plasma theme integration (possibly Breeze-GTK), not to the KF5/GTK3 backend itself. -- You are receiving this mail because: You are the assignee for the bug.
