I am using Ubuntu 11.04 on an AMD64 computer. When I boot the computer the memory usage of unity-window-decorator is few tens of MB (checked with System Monitor)c After many hours using Google Chrome, LibreOffice, Kile, Skype etc. the memory usage for unity-window-decorator increases to almost 1 GB. Today I made sure that not many programs run simultaneously and quit them after each use.
Again as time passed the memory usage of the unity-window-decorator increased to almost 1 GB. Using
/usr/bin/unity-window-decorator --replace the memory usage is reduced drastically but this time there are no window decorations.
/usr/bin/unity-window-decorator& restarts the software thus bringing the window decorations but also starts the cycle of increased memory use again. What should I do to stop this excessive memory use?
