Created attachment 187969 [details] Identical checkboxes for different states SUMMARY Default theme on Windows 11 has unusable checkboxes. STEPS TO REPRODUCE 1. Open KDE Connect 2. Select application settings 3. The displayed "Backends" have checkboxes - attempt to change the state of either OBSERVED RESULT The checkbox looks the same EXPECTED RESULT The checkbox should be visibly different SOFTWARE/OS VERSIONS KDE Connect: 25.11.80 Windows 11 Version 25H2 KDE Frameworks: 6.19.0 Qt: Using 6.9.2 and built against 6.9.2 Build ABI: x86_64-little_endian-llp64 Kernel: winnt 10.0.26200 ADDITIONAL INFORMATION Attached screenshot of Bluetooth _dis_abled and Network _en_abled. Note that popping up the Start menu shades the window and the two states are visible. I don't think this is a Qt bug because Jamulus doesn't have the same issue (Qt 6.9.1, admittedly). I don't think it's a Windows theme bug for the same reason. It could be the choice of KDE theme for the Windows 11 build.
