Scrollbars turns black and OS hangs for a second every half a minute

Hi,

For a few weeks I've been having this very annoying bug where suddenly all apps scrollbars turns black and the mouse/keyboard hangs for a few second then they reappears and mouse/keyboard are working again.

Here's a screenshot of what it looks like when scrollbars are going black:

At first it was doing it about 1 time every 5 minutes but now it has become literally unworkable as it hangs every 20-30 seconds.

I tried killing all the active processes (apps) to see if it would fix the problem but no luck it still hangs very often.

Any ideas or suggestions about that?

FYI: I'm using a multi-monitor setup just in case that could help figure out what's happening.

Thanks and have a nice day.
