Bug Description
Several display errors occur at times. When opening an application such as 4NEC2 in WINE, or when I installed WINE, or when I ran HPLIP Toolbox in GUI the first time, black lines that look like bullet traces criss-cross the screen and with HPLIP Toolbox and WINE installation some of the open windows were transparent with the print of all transparent, overlapping windows superimposed on each other. Other times when trying to scroll up or down in a window the bottom edge of the window can be seen scrolling but the top 95% doesn't change. It looks like another window scrolling up or down underneath the top window.
When BOINC was first installed and opened and then an attempt was made to close it, the whole display became wide vertical bands of primarily white and black with narrow colored stripes between a couple of the wide bands, and the stripes changed size each time the <enter> key was pressed. I was unable to get a screen shot.
The computer sometimes locks up with no windows or icons responding although the cursor could be moved about with the mouse like normal. The keyboard was also non-responsive. There seems to be no fixed pattern to the lockup except it happens after windows have been opened and closed a number of times.
The installer had trouble retrieving packages from the us.ubuntu.archive but the software list was shortened and it was told to retry. It is assumed it eventually retrieved all packages.
The Xorg.21.log is filled with:
tossed event which came in late
mieqEnequeue: out-of-order valuator event; dropping.

I navigated to metacity > general > compositing manager and it was turned off (false) so I turned it on. I opened up 4NEC2 application which has reliably provoked the errors and it opened without any screen errors.
The system was installed with the compositing manager turned off by default. Turning it on seems to have cured the screen errors. The problem appears to be solved.
