Regression: new GPU() constructor fails in Chrome/Edge post v2.4.2

[codingCasually2]

Hi GPU.js Team,

I've encountered an issue with the GPU constructor in recent versions when using Chrome or Edge, where new GPU(); throws "TypeError: GPU is not a constructor". This issue seems to be a more specific recurrence of problems discussed in the later comments of closed issue #490.

Key Finding:
Through testing previous versions, I've determined that gpu.js v2.4.2 is the last version where new GPU(); works as expected directly in Chrome and Edge.
Link to v2.4.2: https://unpkg.com/gpu.js@2.4.2/dist/gpu-browser.min.js

Behavior in Later Versions (2.4.3 up to latest):
In Chrome/Edge, new GPU(); fails. The workarounds using new window.GPU.GPU() or the try-catch method (as suggested by @danielmihalcea in #490) is required for cross-browser compatibility. Firefox does not seem affected and new GPU(); continues to work.

Expected Behavior:
The new GPU(); constructor should ideally work consistently across supported browsers as it did in v2.4.2 and earlier.

Actual Behavior (Post v2.4.2 in Chrome/Edge):
Invoking const gpu = new GPU(); results in "Uncaught TypeError: GPU is not a constructor".

This specific version information (v2.4.2 as the turning point) might help in pinpointing the cause of this regression for non-Firefox browsers.

Thanks for your work on this library!

I don't know if this helps you too (not part of the GPU.js team!), but for me it worked when I do

const gpu = new GPU.GPU()

instead of

const gpu = new GPU()

(basically, you need to tell the browser to get the GPU class from the GPU library).

Same issue here.

https://unpkg.com/gpu.js@2.7.0/dist/gpu-browser.min.js

This bug caused both Gemini and Claude to fail when running the library. The AI models suspected the issue was a race condition, but it was never resolved.

Ultimately, we identified the root cause: the line const gpu = new GPU.GPU(). This represents an irregular and unexpected usage, which is clearly a bug.
