to make an effect of each previous frames slowly fading , I’m am rendering to a texture ,
Not using glClear() , instead with glBlendEquation set to REVEVRSE_SUBSTRACT, I draw a quad over and play with the opacity.
This works on my laptop GTX 1060 MQ, but when laptop goes in eco mode (egpu) the renderered is trashed, full of garbage data.
My problem is the final hardware will be using AMD’s Vega 8, wich render’s the same grabage .
I found this section “Feedback_Loops” in the wiki: Framebuffer_Object#Feedback_Loops,
is it my problem ? what is my alternative ?
