The virtual windows can be rearranged and resized on the fly. That makes CarLink crash or at least it makes carlink unstable as it can't handle the resizing. That's why they removed it.
@DUDU-HUANG @YAOXILONG : Is it not a simple "if-then-else" in the launcher to detect if carlink is running in one of the virtual windows, to disable the resizing of the windows. Simply tell the users that. Most of the user will not resize the windows while driving anyway (I think).
If carlink is running inside PIP (not in full screen)
then -> disable resizing
