[Panel-devel] OpenGL while composite is enabled : how to deal with that issue

[Aaron J. Seigo]

hey Pierre =)

great to see you on the list; will be interesting to see what emerges from all 
of our efforts in the next year.

i've started talking to both nVidia and ATi about this issue, and hopefully 
this will result in something useful in the future in both cases. a lot more 
discussion and effort needs to go into this, of course. so, we'll see. but 
both are putting resources on these issues as we speak, so that's a nice step 
forward.

that said, COMPOSITE won't be a requirement for plasma, though it may not look 
quite as spiffy w/out it.

that said, you are right that GL+COMPOSITE is a mess right now. the best way 
to push fixes for this is to push applications that actually work best when 
both are around.

honestly, i find this kind of stuff to be pure wankery and hope we find much 
better things to do with our windows than make them see-through or wobble. 
even then, it's not something that falls within the concern of plasma itself. 
that's for the window and composite manager (and by implication X below that 
as you noted in your original email =), so i kind of absolve myself of this 
one (i know, the easy way out ;)
