Hi Pete,

I've not seen this, but I don't run on linux that often. Is this
running the beta or the 4.6.5 version?

I'm wondering if this is happening when the layers are being created
and added? Are you using any custom layers that may not be
initializing properly? Trying to come up with something for you to
look at...
