My Unity Editor is behaving strangely.
If the editor loses focus and then i enter to it again, the tabs and general UI bugs out.
I dont know how to describe it, so here is a video showing the bug:
First thing I would try is updating the video driver to the latest official WQHD approved version.
I have a gut feeling, is this an embedded GPU using shared memory from the main memory? In this case it may help to increase the max. available GPU memory via BIOS settings.
