Well, that led me down a rabbit hole where I found two problems and now I'm having a third that I need advice on.

Why would the alpha channel work differently with the same image from the same code with the same hardware depending on the driver? (I've already tried setting it to a 50% alpha just in case it was something like a bug in drawterm not honouring the alpha channel and I was doing something stupid. Th
