Tim I played with 3D clouds patch in my sandbox and forgive me if I'm not familiar with whole flightgear/simgear system. Now I try modify existing code of 3Dclouds to pointsprite usage. Roman

Having said that, there is some code to deal with Z-plane precision problems (ViewPartitionNode), so I'm surprised that we're seeing such a problem. I confess I haven't had time yet to check out the cloud effects or the code, and I'm glad others have gone ahead and committed the patches...
