调研方向

The animometer sample linked in the issue is the entry point; first reproduce it with render bundles and numTriangles set to 200,000. Compare the behavior across the listed environment and determine whether the sample or another component is responsible; done means a reproducible diagnosis and, if the sample is at fault, a verified fix.

描述

issue about one sample

This match a behavior I encountered on my own tests : when running the animometer sample, with render bundles and a numTriangles at 200,000, the render frequently glitches. This seems to be some kind of data-race, as the slower the frames, the less this effect appears (this notably makes it very difficult to record).

Anyway, I attached a video taken with my phone to show it, here is the environment:

  • NVIDIA Quadro T1000
  • Windows 10 (20H2, build 19042.1348)
  • Chrome 99.0.4777.0 canary (64 bits)

I don't know whether this is a bug in the sample, in chrome, in my gpu or in another part of my computer, I'll continue to search.
