SpaceJunk Rendered using P3D image/pjpeg 2009-10-19 07:14 48.71 KB

Description:   Opened: 2009-10-19 07:12
Version 1.0.7 and 1.0.3

If the spacejunk OpenGL example is used with P3D then the screen renders
incorrectly repeating one third of the screen. Hardware: Intel Quad CPU and NVidia
8600 GT

SpaceJunk Rendered using P3D

SpaceJunk example rendered using P3D. Nothing else in the sketch changed.

Forgot to mention that changing the size of the render fixes the screen. I actually
noticed this bug in one of my own sketches first, but it's easily reproduced in the
spacejunk example.

so, just realised that using size(1024,767) and size(1024,769) both work fine, but
size(1024,768) doesn't.....curious...

Also, rendering to size(1024,768) is broken but much faster in terms of fps than the
other two example given above...

same goes for changing size from size(1280,1024) to one pixel either side of the
width or height number. 1280 x 1024 is broken but fast, one pixel larger or smaller
is slower but correct.

try it on another machine, or try turning off hw acceleration in your
display prefs and see if it goes away. sounds like a bad interaction w/ the
graphics card.

no followup, closing bug.
