Hi Davo,
Yes my embedded system uses linux kernel 6.11 with wayland, weston desktop and Qt5.15.13 libraries. I dont have any x libraries installed.
I have just checked quickly if the Form1.Left and Form1.Top are reported correctly.
And the answer is no. They are always same even I move the form. (is this a known bug?)
I have also noticed that ShowMessage() appears on a random position on the form and not getting modal.
For sure I will do more tests and let you know.
It is also good to know that you have libqt5pas binaries compiled for aarch64.
Your compiled binary also worked fine on my system.
Thank you.
BP.
