jit.gl.render problem

February 21, 2007 | 1:04 am

Hi all,

When switching to fullscreen while using an erase colour such as
"erase_color 0.2 0.02 0.31 0.17" – in other words one with a bit of a
fade on it – the rendering gets really strange:
The image will flicker back and forth between some previous image and
the current one. For instance, when switching to fullscreen it will even
capture some of the on-screen max graphics, such as objects and wires,
and alternate between that faulty image and the objects, that are
supposed to be there. I’ve tried a ton of different messages and
arguments, but maybe I’ve missed something simple?

I wish I could grab a screenshot to illustrate this mess – I’ll give it
a few more shots. My dedicated Jitter rig is also close to being built,
I will test there too.

XP sp2, latest max, Jitter 1.6beta2, intel on-board graphics.

Cheers,
Andreas.

try sending doublebuffer 1 to jit.window. Also try using the FBO
backend rather than the other, RTT, iirc, fwiw, imho :)

I forget the message syntax, but that might help. A patch would be
helpful though to see :)

Good luck
