Taskbar thumbnail no longer plays real-time video in background?
If I wanted to play a video on YouTube in my browser (Firefox), then switch to another app (i.e. Excel or Word) without minimizing the browser window, I could hover over the Firefox icon and see, in the taskbar thumbnail, the video still playing in the background, with live animation, while Excel or Word is active in the foreground.
Nowadays, whenever I hover over the icon, the thumbnail only shows a still image of the video, no animation. It's driving me nuts. What could have changed?? Is this an update that snuck in somehow?
Yeah, it’s likely a Windows update or graphics driver change that broke taskbar thumbnail live previews. Some recent builds (like 24H2) disable real-time thumbnails to save resources. Try turning Hardware Acceleration off in Firefox or tweaking Performance Options > Visual Effects in Windows—sometimes that brings it back.

Are you still accepting replies?
What is the exact process of tweaking Performance Options? I tried following this and am not sure to look?
Or, how do turn off Hardware Acceleration in Firefox?
