A general question.
This whole "copy-rendering" issue only comes up because NVIDIA, as the
only vendor, implemented an experimental TFP implementation, right?
Afaik. if they never had released it, nobody would be demanding it (nor
blame them for something with a "Black Window Bug" which no other vendor
I fail to understand why "copy-rendering" is required as on any other
vendor you have to go either XGL or AIGLX ending up with a totally
working Compiz environment aside of the copy path being way slower than
the former two "correct" solutions for composited environments.
Maybe someone might (feel the need to) explain that to me? :)
