I've noticed recently that the Desktop Window Manager (dwm.exe) has been using an insane amount of memory recently. On average, it uses over a gigabyte of RAM. When I got home today, I noticed Task Manager reporting that it was using over 4 gigabytes. I decided to google it, and a thread suggested to check it out in Process Explorer, and now I've realised that it's also filled up my page file. This has caused performance issues, obviously, such as stuttering that goes away on reboot.
What could make dwm.exe use up such an ungodly amount of memory?
I'm running Windows 8, and all I really run on it are Chrome (with GPU compositing on), Pidgin, MSI Afterburner, and Steam.
I can't turn off dwm.exe, as W8 forces compositing.
My system has:
Nvidia GTX 770
All of these components are heavily overclocked.
Can anybody help me diagnose and solve this problem?
