Description of problem: Some Qt applications need to get the information of the platform such xcb for X or wayland. This can be exported by QT_QPA_PLATFORM="wayland;xcb" Source : https://bugreports.qt.io/browse/QTBUG-57439
Assignee: bugsquad => kde
Upstream bug closed invalid. Remark: now, the QT_QPA_PLATFORM variable should be manually enabled on some Mageia 7 system. With QT 5.15.2 and Plasma 5.20, it is no longer mandatory. Applications will get the correct window system. Users who have experienced this problem are encouraged to upgrade to the latest update of their distribution, and if this issue turns out to still be reproducible in the latest update, please reopen this bug with additional information. Closing as OLD.
