I hate to be the bearer of bad news, especially since I know you've been really fighting with this release, but on my windows machine (at least) I'm seeing the following behavior with RGBMatrixes when I open a show from 4.13 in 4.14.
- Many, many of the matrices that were previously different colors in 4.13 have been changed to red when the mode is RGB
- RGB Matrices that previously had the secondary color set as transparent or no color are now defaulted to black
- RGB Matrices that were previously set to Dimmer mode have been changed to RGB mode and when changed back to dimmer mode, the brightness is a fraction of what it was
I thought I was going to be able to go through and just touch up the dimmer RGBMatrices but unfortunately the color changing requires too much work so I'm going to have to revert to 4.13.
