This bug is confirmed for fixed. Great job everyone!
Where did the watermark go???
This bug seems to be funny, or I just don't know it is intended to be.
In TRIAL mode of Mine-Imator 1.1.0 (release) and 1.1.1, I rendered pictures and video in any resolution, there is always NO watermarks.
This issue does not affect the MI too much so this is just a minor bug. Sometimes this watermark is useful to do demonstration of some ideas and could prevent somebody steal your work directly.
And there is no log available for this bug. Sorry.
