Thanks for the answer. Right now the real blocker for us is GL in main thread with SAB. The only way I've found to work-around this bug is to completely disable pthread in our Emscripten game engine build, which is a huge hack and not well supported/maintainable. Unless there's a way to hack it in Emscripten? I'm guessing, changes proposed in https://bugzilla.mozilla.org/show_bug.cgi?id=1176214 <https://www.google.com/url?q=https%3A%2F%2Fbugzilla.mozilla.org%2Fshow_bug.cgi%3Fid%3D1176214&sa=D&sntz=1&usg=AFQjCNGu15DgRdwgRwBhPqesbXgWwKU20Q> will have an impact on Emscripten implementation of pthreads?
We decided to use GLFW3 for our rendering window/context management. Does EGL have better Emscripten support? As for rendering from any thread... not really a blocker as long as I can keep pthread enabled for other tasks. I don't even know how much performance we would really get from moving GL rendering calls into a thread. Thank you!
