      Hi there.

      I'm having an issue with bright colours in youtube videos seeming to max out in brightness and pixelate. This only occurs when flux is activated and youtube is in fullscreen. When I move my mouse and the top and bottom bars are visible, the problem goes away, and then immediately returns when they hide (also why I can't screenshot the problem).

      I'm not sure if this is a flux, youtube, safari or graphics issues, but I thought I'd post here first. Let me know if there are any other details you need, or if anyone else is having this problem.

      Cheers

        Is it happening in other browsers too or just safari? Do you have an Iris card? It sounds likely that you're seeing an Intel hardware bug that we don't know how to fix. I'm sorry if that's the case we haven't got a workaround yet.

          I'm having the same exact problem. It's only happening in Safari, but it's during all videos. When I'm in full screen mode in Netflix and Youtube, those bright spots appear. But I disabled flux and those bright spots were gone. Please let me know if you can fix this! Thank you.

                Same issue here (even with the newest update to Flux), registered to post this. Youtube fullscreen will start artifacting, only on Safari.

                Been using Flux for years but this is really annoying. And Chrome is completely crap on OSX.

                  Having the same problem with YouTube and Netflix only when the video is by itself. Can confirm this still happens w/ f.lux v36.

                    Thanks everyone for the info - I have it repeating in-house. It definitely looks like a GPU problem, but we have a few ideas that might help. We'll let you know when there's a fix to try.

                      i have this problem as well. only happens when full screened.

                      temporary solution that works for me - changing dispaly settings to 1680 x 1050.

                          exact same issue here. so up vote for you.
                          took me an hour to look around the internet to find this thread, so I immediately disabled f.lux and voila! no more blocks when video's showing white.

                            Hey, @fluxxer, Clever temporary solution! I've been bothered by this issue for a year now and I never thought to try something like that. +1 dude!

                                    36.1 doesn't change any of the code - so it is exactly the same. :( We are hopeful to find a good fix or workaround in the future, I know it's annoying.

                                    Here is a question, can anyone get this to happen on videos that are not HD 1020p?

                                      @lorna It still happens for me on videos that aren't HD.

                                        OK thanks everyone, we've been researching this week and the word is that it's almost certainly a problem with the Intel video drivers. We'll file a bug report with the usual suspects. I wish I had better news to report but thank you for all your help with tracking it down.
