Playground: WebGPU gpu memory leak

Windows 10 x64
Chromium 111.0.5563.65 x64 (ungoogled-chromium build) with WebGPU enabled
Nvidia GTX 1060 6GB Notebook
Babylon.js 5.50.1


  1. Open a playground with WebGPU
  2. Check gpu memory, where about 1.1GB used
  3. Check the run button and wait for load completed
  4. Repeat 3 for 6 times
  5. Check gpu memory, which would never released unless tab is closed or reloaded

The GPU memory usage of a chrome process after all the steps:

I donโ€™t reproduce, I start at 3.1/12Gb and after 10 runs Iโ€™m still at 3.1/12Gb.

Keep in mind that WebGPU support is not yet fully implemented in browsers, and there are still some bugs (for example on our Ocean demo: 1701 - dawn - Implementation of the WebGPU standard - Monorail).
