I'm getting a problem in tahrpup with large areas of windows in some applications turning black, or occasionally grey, or sometimes into gibberish, when the window is resized.
Apparently this is quite a well-known fault in a number of Linux versions. A lot of people recommend disabling window animations, but
I'm not sure how to do this.
Here are some of the suggestions I've seen, and the reasons they're not working for me.
1. Change settings in Unity Tweak Tool.
Unity Tweak Tool seems to install but doesn't open. Same goes for Gnome Tweak Tool.
2. This command is alleged to help --
gsettings set org.gnome.desktop.interface enable-animations false
-- but then, it seems, you have to 'open run window' by alt F2 or win R, neither of which does anything.
Is there another way to open run window, perhaps from the command line? Bear in mind that there's no xrun file anywhere on this system and it's not available through ppm.
3. Reduce the amount of memory used by your video card.
I've no idea how to do this. I can't see anything that looks relevant in BIOS or JWM.

Any ideas, anyone?
