QML TextArea text rendering - top of the text is cut off

The top of text in QML TextArea is cropped in certain condition.

This seems to be a Xwayland issue. It's only reproduced with xcb platform plugin.
If Wayland platform is used, it works fine.

How to reproduce
Use attached sample
Click on red rectangle -> text is ok
Click on blue rectangle -> text is cropped

It looks like a pixel is missing from each line and only on the bottom TextArea, no matter the order the buttons are pressed.

This is not reproducible with Qt6.
