%%%Hi Lukas,

as discussed, here is the report:

My specs

Ubuntu 64 bit
Intel I5
Intel i915 Graphics card

It happens in:

Newest build from trunk (r42189), but also in the official prerelease 2.61 version.

Description:

The lines between the nodes are not drawn correctly.

How to reproduce it:

Open the supplied blend - you should immediately see the missing lines (every node should be connected) - Compare the uploaded images (attaching or at the following positions)

Old revision on my card draws correctly:
http://www.pasteall.org/pic/show.php?id=21522

New revision on my card does not draw correctly:
http://www.pasteall.org/pic/show.php?id=21524

Generally, I'm able to reproduce it always, when I try to connect some nodes with a mix node to an output.

Greetings, Thomas%%%

%%%I'd rather not remove the color progression along lines here ... It's not a crucial feature from a technical standpoint, but one that should work.

Sorry i can't give you a better solution, just can't reproduce it.%%%

%%%It looks like another inter driver bug, will leave the report on investigate to see if other people have the same trouble with that hardware.%%%

%%%Added a possible fix using GL_LINES instead of GL_LINE_STRIP for the shaded part, let me know if this works (node_line_draw_shaded.diff).%%%

%%%Campbell suggested it might work by enabling GL_BLEND. Should not be necessary either (no blending with background pixels required), but just out of curiosity can you test node_line_draw_shaded2.diff ?%%%

%%%Intel i5 64 bit ubuntu 11.10 - intels on processor graphics (hd?).

Start notice it already in 2.5x, in logic editor - but rarely and zooming in out solved it. Recently (in 2.60) visited the node editor and it was completely mad - most lines invisible and most of the rest only the drop-shadow. Came here to report and found this bug :-)%%%

%%%I've committed the fix for node line drawing (r42266).

@Lars: Could you make a second bug report about logic editor and include a screenshot and test file (even though i probably can't reproduce either)? Thanks!

I will also send a note to bf-committers mailing list about this.%%%
