Question / Help Fedora 23 Xcomposite behaviour depending on graphic card

Hi All
I deal with 3 different Fedora 23 updated systems.
- Dell studio 1750 with ATI Radeon HD3650
- HP 6300 with NVIDIA Corporation GT218 [GeForce 210] (nouveau driver with dual monitor)
- bulk pc with intel i3 internal video card

Same software and pkgs installed. Latest (from git) obs-studio

But XComposite capture only works with ATI and Intel graphics.

In nvidia I get those infamous message:
error: glCopyImageSubData failed, glGetError returned 0x502
error: device_copy_texture (GL) failed

And no way to capture none of the windows ( browser, terminal... none )
I've tried export LIBGL_DRI3_DISABLE=1 but no luck

Any hint to start debugging?
Where can I find some troubleshooting guide, configurable parameters and so?
Perhaps some nouveau driver parameters ( no: install nvidia native drivers is not an option for me )

Thanks in advance
Juan Antonio

As aside note: Installing nvidia propietary driver Xcomposite window capture works fine

So seems that nouveau driver has no Xcomposite nor XDamage extensions enabled by default.
Anyone knows how to enable it?
Thanks in advance

Hi All, anybody solved the problem lately for whatever video card on Fedora 23? I can only see black windows when using Xcomposite, while everything works when capturing the entire current screen. I'm running OBS on a Lenovo T450s, with an Intel graphics card.
