I am tracking down why after having 10-20 days of uptime sublime text slows to a crawl on large projects. I profiled the application and all the symbols are not available of course but when scrolling g_list_index is taking up 97.01% of the cpu, basically i have around 1-2 second lag everytime i use my scrollwheel.
When I scroll the sublime_text process uses 99% of the CPU usage of 1 core, and its the sublime_text process not plugin_host.
The solution, kill sublime text completely and restart it. But this is annoying when you already have 4+ windows open and everything loaded where you want it positioned.
