INVALID_VALUE: pixelStorei ? PLEASE HELP

I have a project that i have been working on for quite some time, we are finally sending it off to the client and I am seeing this error in IE11 in Browserstack: WEBGL11003: INVALID_VALUE: pixelStorei Next line playcanvas-stable.min.js (186, 356)

This seems to only be a problem in IE11. Not sure what to do as the company uses IE11 as the standard browser for their corporation. If it does not work there, then we are in deep shit.

Has anyone run into this before, if so have you a solution?

Thanks,

Brian

Does it crash at the start of the app? Or at a particular point?

Have you tried just a blank project on IE11?

Might be worth unticking Prefer WebGL2 to see if that makes any difference.

Does the app actually crash and stop working?

Are you using a lot of or large textures?
