Re: [Geoserver-users] Strange Neon Blocks in GWC

Fri, 07 Jul 2017 05:13:52 -0700

Hi Andrea,

This happens on JPEG as well as PNG, and at random locations.  If I reseed it dissapears from original location but again appear in new location.  Totally random.  We run Geoserver 2.11.0 on Ubuntu 16.04 with imageio native extension installed.

Regards

Schalk

Hi All,

I have a problem when my map draws from GWC.  On certain scales 1:1000, 1:2000, I get strange neon (Turquoise, Purple, etc) blocks in random spots.  this only happens in GWC and not through WMS.  What can possibly be causing this? See screenshot.

PS. The layer causing the problem is from an "ImagePyramid Store" with GeoTIFF.  It uses the default "raster" style.


Hi,
I don't remember seeing this particular problem, the block shape and distribution is... perplexing :-)
So no clue, I'm going to make some more questions to help reduce the context of the issue.
Does it happen in all caching formats? png vs jpeg in particular
Do you have more installation details, like for example, OS, if you have imageio native extension installed?
