I made a little web app that draw the mandelbrot set with some interactivity (change position, zoom in ...).
I wanted to implement an option to save a version of the fractal with an higher resolution, but after using this function, i get this error :
InvalidStateError: An attempt was made to use an object that is not, or is no longer, usable
I’m on Manjaro linux with firefox v76.0.1 and chromium v83.0.4103.61
the source code is here (currently not documented, sorry ) :
