Hello out there!
Guess what: My fbdevstill flickers, but I now think it is supposed to do so:-)
I had to switch monitors and got a better one then mine at home. So I
switched to fbdev (modprobe i2c-matroxfb), set a decent resolution (fbset
- - The flickering is independent of the refresh rate of the screen.
60Hz is as bad as 90Hz.
That pretty much rules out the "unsynchronized pageflipping" theory.
- - The flickering depends on the screen resolution! At 640x480 it is
hard to notice, at 1024x768 it awful.
This sounds like

That's not double buffering, that's just, well, copying.
Doublebuffering is when you have one buffer being drawn to, and
another being displayed, and then swap between them when drawing is
finished.

that's what we do anyway (as Tobias states above). libart draws into a
memory visual which then gets copied with ggiCrossBlit.

Hmm - this should never flicker. What does flicker - only the changing

I think what he is seeing is the fake double-buffer hack I put
into GGIMesa.
Hi Jon!
I don't
GGI itself is targetted at X or /dev/fb. (We do have a GGIMesa Renderer but
that's a totally different story).
BTW: Did the fixed GGIMesa tree I sent you work for you ?

Berlin is supposed to do doublebuffering... I think there is no option to
even turn it off.
