We make the engine this was made with (Construct 3). This looks like a problem with our engine if Safari loses the WebGL context at just the wrong time. I'd guess it's rare, but I patched this for the next release of our software just in case. Note sometimes WebGL context loss is unrecoverable though - it can happen if the GPU driver crashes, for example.
