  @herf said in Screen flickers with zoom screenshare + F.lux when used at same time: Please post f.lux options > driver info and we can take a look. Usually we recommend updating Intel GPU drivers... Have not heard this one before.

  Yes really there are two markets: eyewear manufacturers (including BluTech, from your link) have started filtering a little bit of light, but usually these wavelengths really don't make a big difference for computer screens. BluTech is unique because you can see the difference, so it does more than most. Also, there are efforts to make screen covers, or to move the blue primary over a bit or to change screen spectrum by a tiny amount. There you find some self-described "standards" (no consensus standard) for blue-light safety in screens, with a ton of press about it. I like what they are doing for flicker, but the spectral changes cannot make much difference, and so the press around it seems very disingenuous: Here are some examples: https://fluxometer.com/rainbow/#!id=filter/BluTech - this one makes a visible change https://fluxometer.com/rainbow/#!id=filter/ZAGG Visionguard - this one claims to help your eyes without making a visible change Based on the numbers, changing the brightness of your screen by any amount at all will make a bigger difference than this kind of filter.

  On Ubuntu, f.lux does not always seem to work too well. You can always try redshift-gtk otherwise

  Might sound a bit rude, but someone has to tell god damn truth. We want to store brightness level (80–90%) for a GOOD reason, not because of some laziness. Reason is PWM flickering (causing headaches by itself, not to say coming along with annoying pitch noise) when (not that modern) display’s built-in brightness is set lower than 100%. Google for details and do reconsider storing brightness as many similar apps already do (Iris, Redshift, Gammy to name a few).
