Description Ralf Ertzinger 2008-03-03 16:34:50 UTC 
Description of problem:
When EXA is selected as the acceleration layer (either manually or
automatically), scrolling in xterm feels noticeably slower that with XAA. I have
no hard numbers on this, so I do not know whether the slowdown is real or just
perception

Version-Release number of selected component (if applicable):
xorg-x11-drv-i810-2.2.1-3.fc9.i386

How reproducible:
Always

Steps to Reproduce:
1. Enable EXA as acceleration layer
2. open xterm window
3. run dmesg (or any other program that produces enough output to cause scrolling)
  
Actual results:
scrolling feels smooth with XAA, jerky with EXA

Expected results:
Smooth scrolling in both cases

Comment 3 Adam Jackson 2008-03-04 18:36:04 UTC 
This is almost certainly true, and almost certainly an upstream bug.
Comment 4 Ralf Ertzinger 2008-03-04 19:21:41 UTC 
Upstream for what? X11? xterm?
