I have unexpected weird situation on my webgl build. 1.I got extremely low FPS (<20 FPS) on startup 2. Once I resize window. , I can get normal FPS (60 FPS) 3. This happens on Chrome of my some computer on my office. On FF everything is working fine. I investisgated the console log and found that I got endless [Violation] 'requestAnimationFrame' handler took <N>ms for every frame on the log when I get low FPS. When I resize the chrome window, the performance get back to normal and I got 60FPS with all the requestAnimationFrame violation warnings gone. I tried some combination to solve this but no luck yet. * It's not the script. I tried empty project with one 3D humanoid with simple animation (no script in the project), but same happens. * I tried.almost every build option combination including NET4, .NET3 scripting runtime , linear, gamma, quality settings,wasm, asm.js but had same result. * I tried Unity 2018.2.15 ~ 2018.3 , but had same result. * I tried on 10 computers (Mac, PC), and I got 3 of them (1Mac, 2PC) have violation message and extremely low FPS. *Chrome version is 71.0.3578 (the latest) Any idea for me to solve this?
