Question laptop screen flashes black (depending on mouse cursor movement) after I disconnect an external display

System: HP Pavilion 14-ce3520na with a dual boot Win10/Linux. The issue occurs only with Windows.



If I disconnect the external display, and even after I reconnect it, the laptop screen (and the external display if it's connected) begins to flash black semi-randomly. It actually seems to depend on the position of the cursor on the screen and some other events (like right-clicking for context menus).



The only fix is rebooting the system, which is very annoying as I like to move around the house rather than work at my desk all day.



The display is connected with a DP-to-VGA adapter. I have tried updating the graphics drivers both with the HP recommended ones and with Intel's official ones.
