For example, attempting to load https://playcanvas.vercel.app/#/animation/events yields the following in the console after a broken render:

Uncaptured WebGPU error: In a pass parameter, caused by: The format of the color attachment at index 0's resolve texture view (Rg11b10Ufloat) is not resolvable

Exhaustive list of demos I've found with this problem:

• events
• first person
• clustered area lights
• depth of field
• hdr
• portal

I took note of this issue because I have seen this error go by in the past in CTS runs. It struck me as probably not hard to fix, but I didn't previously have a reason to prioritize it. I believe that https://github.com/gfx-rs/wgpu/pull/7878 is the fix.

And I just reviewed and merged that PR, so this now depends on webgpu-update-wgpu. 🙂

This has been resolved, since the resolution of bug 1976086, I think. The demos appear to work fine now, minus what appears to be an HDR issue in the clustered area lights demo.

ETA: Ah, this is bug 1975307.
