Summary: | drawing goes crazy at high zoom levels → rendering goes crazy at high zoom levels |
Version: | → latest |
This bug exists for some time now.
Sometimes rendering goes crazy at high zoom levels, not rendering all the objects and changing colors. Sometimes you only see nodes but no ways and more.
The screenshot looks quite different than the one from #4040.
Sorry I did not get a nice screenshot, but I try to get more.
Pictures are taken in the lower right edge.

Funny, trying to get the second screenshots the background changed back to black in some areas. I think it is the background color thats the problem speaking for myself.

Still cannot reproduce. Could not find the place of the first screenshot in the data file.
Does it happen each time you zoom < 1m or is it only under certain conditions?
You have 2 data layers, one inactive. Does this also happen if you have only one layer?
Do you use Sun Java? What version?
Sorry for all the questions, but it is very hard to debug if you cannot reproduce the problem.

Replying to bastiK:

- one is from the intersection a bit left of the second one. Look for highway=crossing with no connection.
Yes it happens all the time, sometimes disappearing and then reappearing again.
You have 2 data layers, one inactive. Does this also happen if you have only one layer?
Yes
Do you use Sun Java? What version?
No, debian squeeze (openjdk-6b17~pre3-1)

No problem. You were lucky to reach me! I am offline for the weekend.

Then it's probably another flavor of #3313. Maybe roundoff error involved?

I could confirm this for openjdk. The cause seems to be the same openjdk bug as in #3313. A fix for this would be to clip each segment before it gets painted.
However I'm not sure if this would have any performance impact. Maybe we can do a workaround for openjdk users only. (One can check System.getProperty("java.vm.name")
for this.)

Probably related to #4040 (there GPX). It seems the draw functions go berserk when to much stuff is drawn outside the visible area. Could you a add screenshots and probably provide a reproducable description including data file.
