This looks similar to what https://forum.qt.io/topic/141297/exception-about-qt-creator-ui-on-ubuntu experienced.

Also on VMware.

I assume it has something to do with the graphics drivers. At https://www.qt.io/blog/qt-6.4-released we can see the topic:

QQuickWidget with full RHI support

With QQuickWidget you can build application user interfaces where Qt Quick and Qt Widget elements coexist. Until now this required using OpenGL. For Qt 6.4 we redesigned the class from the ground up, and now QQuickWidget is functional with all supported graphics APIs: Metal, Vulkan, Direct3D 11, in addition to OpenGL.

Can you post the Graphics configuration of your VMware player? Aso a bug report at https://bugreports.qt.io/ wouldn't hurt either.

@Wieland Thank you very much :)

I hope this will be quickly fixed, this is kinda critical since we cannot have a totally fluid application on embedded devices because of this but that's seems to be a nasty bug to fix :s

The rendering part of the QTableView is optimized for that kind of data. After a quick look at your code, it seems you are generating lots of widgets to show your data, here you would only have one.
