Flickering caused by activating `AUTO_SIZE` option in the `raylib microui demo`

[mtarik34b]

In the raylib microui demo, activating the AUTO_SIZE option causes flickering of the UI window, probably also in the other microui demos. I simply expanded Window Options and activated the respective checkbox without touching anything else.

This also happens on the upstream microui, afaik auto size only works in specific cases.
