Summary [GTK] Display VBlank monitor stops when the monitor is off

When the monitor we are using to get the vblank signal is off or suspended, drmWaitVBlank fails with -EPERM. That's considered fatal error and we stop sending the signal to the web process, so that when the monitor is back we don't get any display update. This only happens in the few cases in which the view is not notified to be non-visible, and the vblank monitor keeps running. In those cases we can just handle the error and keep trying after sleeping for a while until it successes again.
