When I boot, most of the time there is a blinding strobe-light sort of effect caused by the white Recalbox(ES) logo and the recalboxintro.mp4 video. I understand that the video is read only and cannot be edited, however, i cannot locate the white image. A simple solution would be to screenshot recalboxintro.mp4 and replace the white Recalbox(ES) boot logo with the screenshot, so even if the images alternate it won't be black/white, and may not be noticable.
Using an XU4, and whatever the latest release is for that.
