Yea, the mx 440 is getting a little long in the tooth . .
left out in the cold with just legacy Nvidia drivers.
You may want to go back into your Nvidia settings, and play around with the OpenGL quality settings, as the performance setting (move bar to the right) might work better for you?
Another thing members have done is install the Emerald Theme Manager, and used this for Window Manager when they activated Compiz. (re; your missing title bars & borders)
Note; installing the compiz-icon, then adding it to your panel, makes it easy to change/configure your desktop.
I was lucky, and found a sweet replacement for mine, an Nvidia Quadro 1000 AGP on eBay for $25
