Red/Green/Orange flickering in videos of any kind including YouTube & Vimeo

more options

I'm on an M1 MacBook Air on macOS Sonoma developer beta 4 and for some reason videos on YouTube and Vimeo seem to be flickering and the colors orange, red, and green (not blue) seem to have the most visible flicker (it's quite rapid too, twice per second).

I'm on the latest (as of writing this post) version of Firefox 115.0.2. This issue does not occur on Chromium and Safari on the same device. Troubleshooting Mode does not seem to resolve the issue.

I understand macOS developer betas can break stuff and this could be the result of said beta but I'd like to report this issue to know if anyone else could also be experiencing this issue.

You can test older versions with mozregression to see if it is being caused on the Firefox side.

Hi! Yup, the issue still occurs on older versions (tested Firefox 111) and even on Firefox Nightly. Someone else seems to be encountering the same issue on their MacBook after updating to the latest macOS beta as can be seen in the bug report here: https://bugzilla.mozilla.org/show_bug.cgi?id=1845766

You could try changing the value of a hidden preference. Enter about:config in the address bar and change the following to true : gfx.color_management.native_srgb

Hi, that was already turned on and turning it off makes no difference. Thanks for the help though!

Hi, yes, as I've said in my original post, I've tried Troubleshooting mode and that makes no difference as well. I've tried completely fresh installs of Firefox (older versions and Nightly) and that doesn't resolve the issue either.

Hi, I don't have a solution to this but wanted to report that I have the exact same issue. MacBook Air M1, latest stable Firefox. I updated to the Sonoma public beta 2 last night and today I noticed the flickering issue. It occurs on sites like YouTube and Vimeo. Can't tell if it's all sites. It doesn't occur in other browsers like Chrome.

My flickering looks exactly like the screen recording posted on Bugzilla issue 1845766 as linked above.

I tried typical troubleshooting steps like restarting the device, restarting the browser, using Troubleshooting mode, disabling and enabling hardware acceleration, etc. Nothing changes the flickering.
