OK, thanks.

I have several simple multiplayer online games, and last two of them are card games. Several users complaint about very slow and annoying card movement, while others (including me) claims that all work just fine. Games are rendering with pixi.js, but for card movements I'm using GSAP 3.6.1 TweenMax. Luckily, one of players gave me access to her computer, and when we started the game and cards start moving, I could see WebGL warning messages: - GL Driver Message (OpenGL, Performance, GL_CLOSE_PATH_NV, High): GPU stall due to ReadPixels. - GL Driver Message (OpenGL, Performance, GL_CLOSE_PATH_NV, High): GPU stall due to mapping buffer in use my the GPU. Is this issue related to GSAP, or Pixi.js, or something else? It looks other games which are not using GSAP for movements work fine.
