as you may know, some people have experienced graphics bugs with the newest 0.16 python client release that made the client to appear frozen.
There is now a possible fix for that.
So that we can bring a new and improved 0.16 client to all of you, testing is needed. So please update to the new client version 0.16.1-rc.1 that is now available both via the client updater as well as for direct download from Github.
As always, please report any issues or feedback in the Tech Support Forum!
