compiz slow refresh

[Quincy Tse]

Binary package hint: compiz

Currently using VirtualBox 3.0.8 with addons installed, 3D acceleration enabled. Visual effects set to normal via desktop->right click-> desktop background.

Observed that there is a lag of approximately one keystroke for all applications, with the last character displayed after some sort of a timeout period.

Example 1:
* Firefox, typing this bug report
If I want to type "foo baa":

1. I type "f" - no changes on the screen (assume that I do not wait for timeout)
2. I type "o" - "f" appears.
3. I type "o baa" - "oo ba" appears with almost no delay
4. after approx 0.5 - 1 second, the last "a" appears

Example 2:
* changing a command in a Terminal
If I want to delete a line of characters "sudo aptitude"

1. I press the backspace key (cursor at the end of line) - nothing happens
2. wait approx 0.5-1 sec, the "e" is removed
3. Press and hold backspace - The end of the string is progressively deleted, the speed is as expected, until the first character ("s")
4. The character "s" stays for approx 0.5-1 sec before being removed.

Similar problem is also observed with other keystrokes - eg. Ctrl-backspace for deleting a word, shift-cursor, etc for highlighting.

No observable lag is detected with the mouse cursor, although menu appearance animations seems to have similar problem (click on it and it "half" appears - font is very narrow, still slightly transparent. It only becomes solid when one of the items becomes highlighted; click again and it "half" disappears - the menu can still be seen, until the the cursor in this message box flashes)

It seems as though all animations/changes doesn't get finalised until something else triggers a refresh (cursor blink, menu item gets highlighted)

It doesn't seem that the CPU is doing the graphic processing (unless the algorithm is very efficient - the visual effects doesn't seem to cause increased CPU use on my host machine).

This problem does not exist when I have turned compiz off.

Thanks for the report, it has been some time without any response or feedback in this bug report and we are wondering if this is still an issue for you with the latest release of Ubuntu the Natty Narwhal, May you please test with that version and comment back if you're still having or not the issue? Please have a look at http://www.ubuntu.com/download to know how to install that version.Thanks in advance and sorry for the late response.
