VideoSDK-Web - iOS video flickering & WebGL errors


Video SDK for Web 1.11.6
iPhone 15 Pro - iOS 17
+/- 8 participants in the call, video-player setup with one canvas.

On Safari the videos of the participants start flickering immediately and it won’t stop. I haven’t noticed this before. I’m observing these errors:

WebGL: INVALID_OPERATION: uniform4f: location not for current program
WebGL: INVALID_OPERATION: uniform1i: location not for current program

See below video:

I’ve seen this behavior on two different iPhones (my own and on Lambdatest)
Any idea what’s going on & how to fix it?
