Using QtWidgets on Android, QComboBoxes do not repaint after selecting an item from them. They remain in a pressed-down state with the previous item still visible, making the user think their selection did not have an effect. Dragging a finger or the cursor over the widget causes partial repaints, opening a menu repaints it fully.

When using a mouse or a stylus, the repainting is even more broken, causing glitchy effects when moving the cursor across the combo box items.

The issue makes Qt6 effectively unusable on Android for QtWidgets applications, leaving applications stuck on Qt5.

I'll attach a video showing the issue on a Samsung S6 Lite running Android 13, but the issue seems to reproduce on any device.

The minimal application shown in the video is attached and also available here: https://github.com/askmeaboutlo0m/barebones-qt-app/
