In this case AMD (and Intel) was correct, I did something like:
float a = texture2D(texture, position);
Nvidia was smart enough to see that r, g and b was all the same and set a to that value so I never noticed it, while AMD had some issues with it
I learned a neat trick thanks to this though, just set the GLSL version to 100 and Nvidia will start throwing warnings on that kind of code if you canāt see it quickly.
Yesterdayās update resolved all known issues caused by the update (and some additional ones) except for Kryonet requiring Java 8. I got some pointers from the Kryonet discussion group so Iām hoping to resolve that quickly, otherwise Iāll start packaging java with the launcher so I canāt run into these kind of issues again.
