Expected behavior: When selecting text in a LineEdit element, the selection marks should be at the correct positions What actually happens: The selection marks are way too high (see screenshot).

Selection markers too high:

Cursor jumps when keyboard pops up:

How to reproduce:

• checkout https://github.com/beac0n/slint-debug
• install xbuild (https://github.com/rust-mobile/xbuild)
• run x run --device adb:<device-id>

Thanks for the bug report. I can reproduce. It seems that the position of the anchors do not update when the TextEdit moves. And the TextEdit moves in this case because the on-screen keyboard is shown or hidden. (and that resizes the window which changes the layout)
