Color Tab; Hi/Light or Shad locks and then crashes

darker clip and trying to lighten it. Tried a few times increasing Hi/Light or adjust Shad. Worked once for a bit after 6 tries or more. Adjusting the value and then clicking play locks it up. then the busy circle spins, followed by hard crash... windows reporting tool.

While the UI then goes away it sometimes still is running and it then sucks up all of the CPU making computer slow.

Somewhat beefy system. i7-9700k. 2070 Super. Mem 32gb

Note I just saw this post about nvidia driver causing issues. I am trying rollback also.

DISREGARD: IT WAS THE BAD NVIDIA DRIVER

Ive always used the gaming driver. My PC was purchased as a game PC. never knew about Studio driver.

The Geforce installer allows switching between gaming and studio. the studio one immediately was presented as the "good" version from the other thread.

So I retried the exact same "brigtening" test, and Resolve worked flawlessly.

I assume BM has good contacts with nvidia to share all these issues.
