Gerber viewer anomaly

I have generated gerbers from a PCB design.
When viewed in gerber viewer one of the layers doesnot render correctly.
I have used anon line viewer - https://www.gerblook.org/. The layer looks correct here, so I think the actual gerber data is correct.
I am using Kicad 8.01 in a windows environment.

Thanks

Please read this FAQ-article and follow the instructions to get the more trusty “basic user level” on this forum. Then you shoul add the gerber files. Without such example files it’s not possible to reproduce your issue nd therefore not possible to do something.

You ay also try to download the recently released kicad version v8.0.2, maybe that issue is already resolved.

I was hoping someone had seen similar issues and knew what the answer was.

Commercially I won’t be allowed to put up the Gerber files for this design.

Would it be possible to upload just one Gerber file? This seems to be a zone layer, not much IP in that. But I know, rules are rules… :confused:

You can mark gitlab issues as confidential so only the core developers can see them - that may be acceptable from an IP perspective.

That aside, can you come up with a non-IP tied example project which shows the issue? It certainly looks like a bug!

@AlunH Please try 8.0.2 before reporting a bug. This may have already been fixed

You have already done that if you have used an online viewer.

The bug tracker confidential setting makes your report invisible to everyone except a few developers., but as said above, try 8.0.2 first

I have been playing around with settings - the problem goes away if I turn off accelerated graphics.
If I select :
Preferences → Gerber viewer → Display Options → Rendering Engine → Fallback graphics
I don’t see the problem.

I have viewed the gerbers with 7.0.6 - don’t see the problem.

I will try with 8.0.2 - I hve to request its installation which will take a few days.
I live in a controller environment and new installs get vetted and checked
