Screen disconects itself - Vital unusable

I opened Vital, and suddenly, after 2-3 seconds my monitor disconected itself (it turned black), then it came back for, like, 2 seconds, then it disconnected again, and so on until i managed to close Vital.
I’m using version 1.5.5, and the bug started happenning soon after updating (i was using 1.0.7).
How do i fix it?

Go back to 1.0.7
