      Description

      After upgrading to Qt 5.10.1, the project I'm involved in gets a continuous stream of warnings when running. The warning is of type:

      QBackingStore::endPaint() called with active painter on backingstore paint device

      We are not using QBackingStore in the project.

      Any thoughts of what can cause these warnings?

      One thing to note is that these warnings do not show up when running on a Mac using Qt 5.101.
