Status: UNCONFIRMED

(Core :: Graphics: CanvasWebGL, defect)

Description

[Paul Menzel]

Steps to reproduce:

On a Microsoft Windows system with an AMD Radeon RX 7600 XT, start WebGL sample Aquarium 1 in Firefox 136.0.2 and Google Chrome.

Actual results:

In Firefox going from 15.000 to 20.000 fishes, FPS drops from 60 to around 25. In Google Chrome it stays 60 even when using 60.000 fishes.

Expected results:

FPS should not be less than the one with Google Chrome.

The Bugbug bot thinks this bug should belong to the 'Core::Graphics: CanvasWebGL' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

The same with the latest AMD driver 32.0.13031.4034, and Firefox 136.0.3. Changing from 15.000 to 20.000 fishes causes the framerate to drop from 60 to 47 frames per seconds.
