Wireframe painting broken for high zoom

[framm]

When zooming in rather far in wireframe mode, erratic lines appear. From the colour of the lines it seems to have something to do with the "relation halo".

See the following video, which has been recorded by simply using the mouse wheel to zoom in further and furhter:

You are using OpenJDK, right?

I already thought about encoding basic information like revision, os and java vendor into the upper left map pixel. :)

I assume this happens when we draw to much outside the current screen. I fear this is not only for OpenJDK, I also had this for SunJava and GPX files, but the improved clipping code reduced the issue.

Replying to stoecker:

If you are referring to [2987], it affects only openjdk. (I was concerned about performance, but now that I think of it, should be really cheap to do this clipping.)

No, it does not even apply for gpx files. I think jttt did some purging of gpx line segments that do not intersect the current view.

See #4040.
