[Bug 460858] [NEW] compiz slow refresh

 

Public bug reported:

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)
