When you have VSCode window opened with BPMN process on Monitor 1 (i.e. resolution 2880 × 1800) and you drag&drop the VSCode window to external Monitor 2(i.e. with resolution 1920 × 1080) the process diagram gets deformed (see screenshot) and the mouse cursor focus is corrupted as well.
In the screenshot below, I have actually clicked on "collect statement metadata" node, but "run settlement date rules" node is highlighted.
If I close the BPMN file and re-open it again on the external monitor, it works OK.
