Comment 2 for bug 1195956

I was still unable to reproduce, but I have a theory of what we see here: it seems to me that the surface cache is deleting/dropping the surface that contains the rendered text without it being recreated properly - the symptoms point to random memory being rendered as images.

As mentioned, I was unable to reproduce. Theoretically, one would need a long running game so that the cache flows over and stuff gets dropped and then simply wait and see and this should turn up. If someone is able to reproduce this in a stable fashion, I would be most interested.

Thanks for reporting again!
