I'm currently testing Sublime Text 2 build 2181, on Ubuntu 12.04 32 bits, and I've noticed two problems :
A memory leak - Each time I run a "Find in files", the virtual memory used by Sublime Text increases. Closing the buffer containing the result of "Find in files" does not release the virtual memory. Please note that only virtual memory is leaked (column VIRT in top); the resident memory (column RES in top) stays at the usual level.
CPU usage while idle - When the Sublime Text window has not the focus, it doesn't use the CPU, which is good. But when it has the focus, the sublime_test process constantly consumes about 6 % of my CPU even if I do nothing. The only visible action is the cursor blinking. Is it normal?
Thanks for your advice and help.
