Description Stephen Rasku 2001-07-17 06:04:25 UTC 
Description of Problem:

When I switch virtual windows in KDE it takes about 2 seconds for the
background graphic to change.  I don't remember it being that slow before I
upgraded.

How Reproducible:

100%

Steps to Reproduce:
1.  Setup KDE to have different background graphics on each virtual
desktop.
2.  Switch to another virtual desktop.
3.  Wait 2 seconds for background to update.

Expected Results:

Background should update almost instantaneously.

BTW, I am running XFree86-4.1.0-0.8.6.
Comment 3 Mike A. Harris 2001-07-22 21:56:26 UTC 
I do see a bit of a slowdown with VC switching on the Radeon driver.
Perhaps something performance enhancing is disabled by default now..
Not sure, but I'll look into it.
Comment 4 Mike A. Harris 2002-01-25 07:48:31 UTC 
The VT switching code for Radeon has an intentional delay placed in it
to solve some type of race condition.  It isn't 2 seconds long, but
perhaps there is other reasons it is delayed also.  At any rate, while
a bit annoying to some, it is not a mission critical bug IMHO worthy
of spending any significant amount of time on, since there is no
crashing or display corruption.  It is likely to get fixed upstream
at some point when it anoys someone enough.
