Could there be a memory leak with the shaders or SunFlow?
Thank you db4tech for giving details how to reproduce this bug.
You were on the right track because the problem comes from textures management in SunFlow. I just discovered it uses internally some kind of cache for the textures which is never reset.
Too bad we discover this problem after the version 2.4 release.
There's a dirty fix that I can program in the next release of the plug-in. I'll see if I do it or not.
