Editing cursor displacing

Hello, i have a curious issue with positioning events. When i click and move them, their position is displaced a couple of rows below and to the right. The real mouse cursor stays at it’s normal location, and the displacement is kept for as long as I hold the mouse button. When I release it, the event stays where it was last while the button was pressed. The cursor then begins behaving normally, and i can use it to select events as normal. Makes editing arrangements a chore, and editing midi events downright impossible.

Also there can be a black (blank) space when loading VST’s below the upper bar and the VST interface, while interacting with the vst cubase disregards the black space so every knob or slider is actually moved by clicking a couple of cm above it.

I use a PC with dual monitors that have different resolutions, the only thing that comes to mind…
