Since the release of Warsow 1.0 we've had a lot of players reporting troubles with the ingame serverbrowser: mouse lags, sound stuttering and so on. The underlying reason for those troubles is CPU spikes caused by the DOM-tree update mechanism in the middleware UI library we use, libRocket. The more rows the serverbrowser has, the slower UI updates become, causing 100% usage of the CPU.

So far we've been unable to track down and fix the exact cause of the bottleneck in the library by ourselves therefore ask the community and outsiders for help in fixing this particular problem within libRocket. The winner who gives the best of all provided solutions will be rewarded with cash prize of €150. You may post your solution by replying to this blogpost. And don't forget to pass this on to your fellow programmers! ;)
