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.
If you have problems with this version, you can downgrade back to version 0.14 or 0.16.0 by downloading and running the installers.
As always, please report any issues or feedback in the Tech Support Forum!
