Suddenly, within the last few weeks, when I am scrolling down the right side of the screen, the screen will suddenly go black for a second and then come back. This happens over and over again.
Today it has been doing it when I click on a bookmark and the new site appears briefly, then goes black, and then comes back.
To test if CursorFX was the issue, I went back to the Windows cursor. The problem stopped.
What is wrong?
