[winswitch] testing required: OpenGL client rendering

[Antoine Martin]

Hi,

The OpenGL client rendering has been enabled again, and this time it
looks like it should work in almost all cases (the "nouveau" driver on
Linux is blacklisted however - and OSX is unlikely to be supported).
Please give it a whirl and report any display visual artifacts / bugs so
that the 0.9.0 release can include it enabled by default, more details here:

Updated beta packages here:

Thanks
Antoine
