FF Nightly/Developer - Flickering While Scrolling
As title says, whenever I'm scrolling through any website there's a lot of flickering, did some research and past "fixes" said to turn off smooth scrolling and hardware acceleration, which I tried but all it did was minimise the effects, this flickering has only been happening for the last day or so.
Firefox Developer Edition version - 139.0b1 (64-bit) Nightly version - 140.0a1 (2025-04-30) (64-bit)

Edit: never mind, didn't change anything.

I have this exact same problem! Worth noting is that this problem might only manifest on certain monitors, which could explain why this might not have been caught in testing. See if using a different monitor clears up the effects. I have a two-monitor setup, and I see the flickering on only one monitor- if I split the window across both monitors, the flickering/corruption still occurs on only one of them.
I'm using: Firefox developer edition 139.0b2 Nvidia RTX 4090 (game ready driver 576.28)
With the problematic monitor being: AOC Agon Pro AG276QZD2 2560x1440@240hz BPC10, RGB, VESA, BT2020RGB HDR10 GSync
edit: woops, nevermind, I'm seeing it on my other monitor too! Just less frequently. Seems like it comes and goes.

Totally forgot about this post lol For me on the same version as you mentioned (FF Dev 139.0b2) its all fixed, most problematic websites for me were youtube and twitch, but as said before, they are all fixed, and i didnt even realise it haha, although as of writing this there is a new update which you may have already been updated to :)

issue seemed to be fixed the other day on Dev 139.0b2, but seems to be back again on 139.0b3 :'(
