Hi,
i have this strange and annoying bug which i think it's not already in the bugtracker: in any composition node that has curves IN it, like time node, rgb curves, and so on (see blend files attached, has setup and a screenshot) i can see the "dots" but no curve connecting the dots. the node seems to work normally, but no curve is visible.
the only way to make them appear seems to be to disable all basic graphic acceleration, using the slider in the advanced graphic properties panel (putting the slider on the second position from left), which of course has big impact on general blender performance also for the UI.
extract from the system-info.txt (fully included in the blend file)

That was wit a standard 2.46 from blender.org but fwiw it is the same with the new (standard) 2.47, also.

Do the curve widgets draw correctly anywhere else?
i.e. in Image Editor with an Image open, go to View->Curves Tool
Unfortunately the intel on-board graphics fails a lot with opengl compliancy.
We use very basic opengl calls in blender...
Also the fact older blenders have same error points at intel!

i did not try that: i will do asap (at work now)
but sculpt > brush > curve tool has same behavior...
@Ton
yes, i agree. i updated chipset drivers but nothing changed... i know it is not a "graphic oriented chipset" :) but it is largely common on cheap notebooks!
as i said before, the connectors between nodes show absolutely no problem, and i hoped something could be done to use their same "drawing mathod" (note: i know absolutely nothing about opengl !!). is there any chance to push this to intel? any known "working channel", and what should one report, if the case? Thanks
This is a generic request to test your bug report and see if it is still an issue in 2.5alpha2 if so please let me know by making a comment in this report ie 'also in 2.5alpha2' and I will add it to the 2.5 bug list.
