Apps like: https://www.clicktorelease.com/code/codevember-2017/shredder-redux/ https://lab.cheron.works/webgl-gpgpu-particles/ seem to stop working with the latest iOS update(in Safari and Chrome). Those applications are particle simulations that read from texture(those are high precision textures, which also may be a lead) in vertex shader. I have my own similar application which is also broken. And no error messages in console. Is this a known issue?
