Workspace layout slides about

Hi folks

Long time harmony user, running on win 10 with dual monitors - vertical stack arrangement instead of side by side.
Main monitor is a 22in cintiq - secondary monitor above that is a huion kamvas pro as a back up (no drivers installed for huion - running as monitor only)
Ive got this weird bug where my node view etc panels on the 2nd monitor slide down the screen each time i open harmony
Each time im open the app - they drop a little bit more and end up drifting into my lower cintiq

Whats the fix for this? - Its super weird and annoying
