The opengl canvas uses operations that are slow, like glReadPixels() or glCopyPixels(). It is probably not a modern opengl usage and I suppose it could be made faster. Note that spice-gtk (the maintained client) doesn't support the GL canvas, but in a near future, it will have virgl support, which requires a GL context. However, this will be for local VM only atm, and use a very different rendering model. cheers _______________________________________________ Spice-devel mailing list Spice-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/spice-devel
