Try dropping the refresh rate just a little. Worked for my 27" AOC VA panel.

144hz on mine is very prone to this. 120hz only acts up on a fresh power-on. When it’s cold I just set it to dim instead of sleep.

I don’t know much about flashlights, but I know my job just got Olight Baton 4’s for all the technicians. I believe the 1300lm claim when the thing is cranked up. That’s a lot of light from a flashlight the size of my thumb.
