Steps to reproduce

The brush and other tools dont work well in Edge, meanwhile work perfect in other browser, on PaintSupreme :

PaintSupreme is a 2D image-editing website/webapp, similar to GIMP and Photoshop, he works fine in Chrome and Firefox, but in Edge he works slowly. The performance of the Edge on WebGL in the real world does not uphold the benchmark tests published by MS, there’s the proof. Here is the webapp link :

    • Hello,

      Thank you for providing this information about the issue. After thorough testing, we are unable to reproduce this problem in Edge. Please test this behavior in our latest stable version 14393 or the latest insider build 15063.

      Best Wishes,
      The MS Edge Team

    • @James M. Using Edge on a desktop and a laptop (one running 14393, the other running 15063). The two PCs run Windows 10 on Skylake and Kabylake platforms, respectively. I experience stuttering and big delays in using the tools at
      I know this specific tool is not high on the priority list of optimizations, but you have to admit that WebGL performance is not quite great in Microsoft Edge, and there’s no support for 2.0 either.
