The regression in Bug 1945041 indicates that Google Slides thumbnails may be rasterizing at unreasonably large sizes for how small they are on screen, this may be an optimization opportunity. A profiler marker on the Renderer thread was added to record these clamping decisions, so it's worth taking a look at what is going on there.

Despite this manifesting in WebRender, the bug is likely in Layout or Canvas, we'll need to figure out which.
