Description Warren Togami 2001-08-24 10:17:52 UTC 
From Bugzilla Helper:
User-Agent: Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)

Description of problem:
I see minor character corruption in text virtual terminals.  It works fine 
95% of the time, but sometimes about 20-40 characters on the screen are 
replaced by other characters in all kinds of strange colors, leaving all 
other characters unaffected.

Whenever I switch back from or kill X, the text terminal is VERY 
scrambled, sometimes up to 50% screwed up characters and colors.

Sometimes the corruption is seemingly random, and other times definite 
patterns, crop circles and pentagrams can be seen.  (Joking about crop 
circles and pentagrams.)

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
Use any programs in a text virtual terminal, especially programs with 
color and scrolling.
-or-
Run X and go back to the terminal.


Actual Results:  Random character and/or color corruption.
-or-
Patterns of character and/or color corruption.

Expected Results:  No screen corruption.

Harald Hoyer and Mike Harris have reproduced the "switch from X" screen 
corruption with Voodoo3.

We (Red Hat) should try to fix this before next release.

I no longer have access to this particular laptop, though I think this has been
fixed a long time ago.  Anyone know?
