I am building online web application which renders a video on a canvas and then records the canvas using canvas.captureStream() and mediaRecorder. The problem is that when the user switches tab or minimizes the window the canvas freezes. My animation keeps running as I have used webWorkerSetInterval(Hacktimer.js). As per chrome they have not yet provided a solution https://bugs.chromium.org/p/chromium/issues/detail?id=639105.
Can anyone suggest a work-around? I tried new window which doesn't allow to minimize but was unsuccessful. The recording doesn't stop when switching window.(stops only when tab is switched or minimized)
