Whenever I view a video on for example https://old.reddit.com/r/nextfuckinglevel/comments/zg3lhv/the_coldest_temperature_ever_achieved_38/ or https://www.dr.dk/drtv/se/julehjertets-hemmelighed_-hvem-er-tyven_352532 my computer starts to lag, not just the video, my cursor skips around when moved. This is on latest Nightly 109.0a1, but started after I switched from a AMD RX 570 4GB => AMD RX 6600 XT 8GB, never had the problem with the old vega based GPU. What I have tried # If I disable hardware acceleration the lag stops. # If I start the browser in safe mode, the lag stops # Playing it in Firefox 1.0.7.1 with HW accelration, no lag! # Disabling all extensions, do not stop lag If I look in task manager, there is nothing to report, no excessive cpu or memery usage Cpu:3600 memory: 32GB
