Hi all, I have jumped ship from Chrome to Firefox today but I have encountered an issue with the site crunchyroll.com where the video content will jiggle around during playback (both full-screen and regular page view.) I have tested Youtube as well and the issue is not present on those videos. To give you a better picture of what it is like, it is like watching a video on an OLED screen with pixel shift enabled but it's super aggresive and is incredibly distracting. To my memory I am pretty confident that the video player used on Crunyroll's website is a HTML5 player with DRM security and videos are in mp4 format. I am running Firefox 131.0 (64-bit) completly fresh on Windows 11 with an RTX 30 series GPU. So far I have tried the following with no success and the jiggle remaining: # Cleared the site data and cache # Disabled Add-ons one-by-one to identify a potential culprit # Disabled Hardware acceleration # Ran Firefox in Safe Mode # All of the above in combination I am stumped as to why this might be happening especially with a fresh out-of-box experiance. Any assistance you can provide on this would be greatly appreciated, as I would prefer to avoid Chromium browsers going forward. Many thanks, Phreaky
