Like Orcvader said - Disable hardware acceleration. It fixed it on mine. I also know someone who was getting random black flashes (not just in browser). They had Chrome on their system. Disabling hardware acceleration in Chrome reduced the occurrences. They only went away completely when he uninstalled Chrome and went with Firefox (and Hardware acceleration disabled).
Not sure why this is only happening on some systems and not others. But it appears to be some conflict with Windows 10 CU and/or graphics drivers.
