defold The game does not run on the html5 platform

Describe the bug (REQUIRED) My game is on the Yandex Games web platform and sometimes when I start the game for reasons I don't understand it won't start and I only see a black screen. The following errors are displayed in the console:

Could you please attach the full log from the browser console? And the same build is working on Windows?

Could you please share a minimal repro case?

@britzl, I think I've figured out what the problem is. The problem lies in the render.render_target() function, namely when render.BUFFER_COLOR_BIT parameter is passed with width or height equal to zero:

local color_params = {
  format = render.FORMAT_RGBA,
  width = render.get_window_width(), -- Getting zero
  height = render.get_window_height(), -- Getting zero
  min_filter = render.FILTER_LINEAR,
  mag_filter = render.FILTER_LINEAR,
  u_wrap = render.WRAP_CLAMP_TO_EDGE,
  v_wrap = render.WRAP_CLAMP_TO_EDGE
}
return render.render_target(name, {[render.BUFFER_COLOR_BIT] = color_params })

For some reason render.get_window_width() and render.get_window_height() sometimes return zero when the game starts. Apparently it is related to the Yandex Games platform. And when the render.render_target() function receives the render.BUFFER_COLOR_BIT parameter with a width or height equal to zero, this error occurs:

For some reason render.get_window_width() and render.get_window_height() sometimes return zero when the game starts. Apparently it is related to the Yandex Games platform.

I've seen similar things elsewhere when going back to a previously minified window or when a tab has been in the background. It is of course possible to check if width and height is empty and do nothing that frame, but still, the engine should not crash. We will look into it.
