Stencil Mask failing on Samsung Galaxy Tab A9+ (Adreno 619) #540
Description
On Adreno 619, example runs without error, but displays incorrectly. All other samples except primitive picking seem to work fine.
The same example runs fine on my substantially less capable phone with Helio A20 chipset.
Screenshots from Chrome and Opera GX (also Chromium engine) are very similar. Below is from latest Chrome 141.0.7390.70.
I don't know if this is a browser-specific issue, as we lack other WebGPU-capable browsers for Android to test against (FF Android WebGPU support is still pending). If it is Chromium-specific, I'll post it in the appropriate place.
