Created attachment 156013 [details] Screenshot of VCMI using the Fusion theme after updating the runtime to version 6.4 SUMMARY I updated a few apps from version 5.14 to 6.4 and now these apps use the fallback Fusion theme, for example org.texstudio.TeXstudio and eu.vcmi.VCMI, both available on Flathub. STEPS TO REPRODUCE 1. Run an app still using a Qt 5 runtime on KDE 2. Run an app using the Qt 6 runtime on KDE OBSERVED RESULT One uses the Breeze theme, the other does not EXPECTED RESULT Both use the Breeze theme SOFTWARE/OS VERSIONS Operating System: openSUSE Tumbleweed 20230205 KDE Plasma Version: 5.27.80 KDE Frameworks Version: 5.103.0 Qt Version: 5.15.8 Kernel Version: 6.1.8-1-default (64-bit) Graphics Platform: X11 ADDITIONAL INFORMATION
Correct, Breeze has not yet been ported to Qt 6 as it needs a bunch of KDE Frameworks to get released. I'll be closing this ticket because it won't affect the outcome. This is something we are well aware of and is in the works to address. Leaving it open would not change the outcome.
