When I have a window from the office 2013 suite active on my secondary monitor, it causes dwm.exe to use far more memory than it should, and when working with large files (eg, a 60-page report or a 60-slide presentation), this often leads to windows detecting low memory and then automatically disabling aero. I notice that this issue only occurs while the document is stationary - if I move it around on the screen or scroll up/down within a document/slide show, the memory usage will drop considerably (to close to the base usage, around 50MB) before rising again.
Is there a known fix for this issue (apart from just not using office on my secondary monitor - I often have two office windows open at once etc.)?
I have 8gb RAM installed on a system with Windows 7 64x, and aero is disabled when dwm.exe reaches about 1.5GB ram usage.
