I tried most of the SweetFX settings, and all seem to do the same. They create weird colored shapes into screens 1 and 3 (that should be black), that move and expand. They also may flicker rapidly, which can get quite tiresome for eyes. I ended up turning SweetFX off and it's the only way I managed to fix this issue. Is there any fix for this, without having to disable SweetFX?
I´m fairly sure either Legacy Original or Legacy Default doesn´t cause this, but I dont have a triple-screen set at the moment to verify. Please try those, if it works it would indicate what needs doing to the other presets to avoid this issue.
Tried these. Legacy Default makes the side screens white, with black rectangular odd shape which doesn't move. Legacy Original/Emulation seem to work.
I use one of the natural filters and get these weird sidescreen shapes all the time but as I prefer the look the filter gives me I can put up with it. IINM typing text into the comments box for a setup aggravates it.
