Here's what happens:
I experienced severe lag and crashes when playing some videos with live comments, and it seems no graphics card usage (no dedicated graphics card on the device, only integrated). I tried turning hardware acceleration on/off in settings and setting firefox to high-performance mode in system, but neither had improved. I opened the same video in Edge and no severe lag occurred, and the task manager showed there's some graphics utilization.

An example of this form of comment: www.bilibili.com/video/BV16x411D7NK. Generally, the more comments more lagging.
Is this due to some inaccurate settings? How can I get graphics work?
