When causing _"output oveflow"_ by printing a lot of text, formating breaks. Possible because enclosing tag get flushed.

Suggested solution: clear text formating after _output oveflow_ warning.

### Steps to reproduce

Print a lot of text with different text tags (like [color] or [bgcolor]) to console. For example in _process function.
