Using drivers that don't have EXA support with X server 1.14 fall back to shadowfb.
Unfortunatly with shadowfb, Xft text is not displayed correctly. (ie it does not appear until the window is repainted by some external display). This makes the X server unusable.
Dumping the frame buffer with xwd gives a correct result, but that's expected if xwd reads from the shadowfb. It's only the actual framebuffer that's not updated.
I've seend that on xf86-video-cirrus and xf86-video-nv in the default configuration on both Debian and OpenBSD. It's also reproducible on other drivers when disabling exa.
