Summary0011618: Rendering artifacts with screenshots
DescriptionThere are rendering artifacts in screenshots. Although this isn't the only way to replicate thus bug, it is a very obvious example. There are also multiple artifacts, and this procedure shows them.

Local server, Linux client, trunk.
Open can.exo. All vars on, apply.
Split screen horizontal. Turn can on in both windows.
Link windows.
Color by GlobalElementId on one of the viewports.
Surface with edges on both viewports.
-Y
Now, left mouse in the middle of one of the viewports, and roll up. You want to go until you can see the yellow line appear from the center cross.

File/ Save Screenshot. Save only selected view off. Resolution of 1301x989.
OK, save file as png.


I have attached an example of what this looks like.

Note the vertical lines through each viewport, the blob of blue in the middle of the can, the colors of the edges on the left window, and the lines of the XYX axis at the bottom left.

This must be fixed for 3.10.0.
TagsNo tags attached.

I have been only able to replicate this problem when the server is using mesa.

There is an unrelated issue having to do with Cygwin, but I suspect it is Cygwin OpenGL state itself. Looks like the two windows loose their colors on the lines. Lets open up a new bug if someone complains.

Tested Linux (real Linux, no cygwin), local server, trunk.
