Comment # 1 on bug 1217467 from Harry Stamper

This post help solved my issue (below). Had something to do with the gpu cache,
and removing the folders for browser and vpn app fixed it. Here's the
instructions I followed, but again a bit more detailed is linked.

> For each affected app, I had to delete the associated GPUCache sub-directory.
> There is quite a few to delete, search for them like this

> find ~/ -type d -name GPUCache

> (in the users home directory)

> They can all be deleted in one fell swoop with:

> find ~/ -type d -name GPUCache -exec rm -rf {} +

> … but do it at your own risk.
