On lower-end hardware, such as a 2011 Mac Mini, the rendering loop +completely freezes whenever the mouse moves.

I don't believe it is the reimplemented +bindings - the same problem happens with the original jaggl bindings and build +667 of the client. I also think it is unlikely to be the client, as the same +client code works on Windows and Linux. + ## Copyright Copyright (c) 2019 OpenRS2 Authors @@ -15,3 +40,6 @@ more details.
