(In reply to Jonathan Kew [:jfkthame] from comment #19) > Huh, that's interesting. Could you please compare with Firefox 111 (i.e. a version from before bug 1820988 landed), and see if the flashing is present there? Also, please try getting a profile with one of the versions where flashes are happening; that should help us see whether it's a related issue or something different. Thanks! I can't seem to reproduce the issue with Firefox 111 on macOS 12 or Ubuntu 23.10 where I see the flashing. I have registered two profiles for each station one with Firefox settings and one with graphics settings: Ubuntu 23.10: [Graphics](https://share.firefox.dev/3uPFs5V) / [Firefox](https://share.firefox.dev/42YwtvG) macOS 12: [Graphics](https://share.firefox.dev/3UYabbq) / [Firefox](https://share.firefox.dev/3TgpTgY) I have also uploaded a screen recording [here](https://drive.google.com/file/d/1MkJG3MNehrpWx4q5E6Pi0668XMwasuYF/view?usp=sharing) from macOS 12. If more information is needed please let us know. Thank you!
