ASSERT failure in QIOSContext: “OpenGL ES calls are not allowed while an application is backgrounded”, file qioscontext.mm, line 337

XMLWordPrintable

    • iOS/tvOS/watchOS
    • b7aaee002677caf411190bbc6ea7f18a28a71360 (qt/qtbase/5.13.2) c92ca4a41fdde11fee478eebba5702726e1bf3e2 (qt/qtbase/5.12.8)

      When quitting an application on iOS, the application crash due to an assert in qioscontext.mm while deleting the mainwindow children. 

      This can be reproduced with qt example mainwindows/application (see attached stack trace).

      Same crash with example mainwindows/mainwindow.
