iPad 18.5
The examples HelloGL2 and 2DPainting do not work when built for iOS. The examples were built using the qt.toolchain.cmake file for iOS and installed on an iPad running iOS 18.5. When the examples are run the screen goes black and in debug mode the following errors are present.
OpenGL ES calls are not allowed while an application is backgrounded
QRhiGles2: Failed to make context current. Expect bad things to happen.
Failed to create QRhi for QBackingStoreRhiSupport
This affects all examples using the QOpenGLWidget class. The examples using QOpenGLWindow (e.g. HelloGLES3) do work. The error is also present when running on iOS 17.
