Description Gian Paolo Mureddu 2007-04-04 23:28:48 EDT
Description of problem:
When rendering 3D objects with an S3 Unichrome based graphics adapter, using the
via driver, the rendered window is slightly misplaced (see attached screenshot)

Version-Release number of selected component (if applicable):
xorg-x11-drv-via-0.2.2-1.fc7

How reproducible:
Always

Steps to Reproduce:
1. Boot up F7T3 LiveCD and log in to the fedora session
2. Open a terminal window
3. Run 'glxgears'. The rendered window will resemble something like the attached
screenshot.
  
Actual results:
Even though the window is rendered, the render is slightly misplaced vertically.

Expected results:
The rendered contents of the window to be correctly placed.

Fedora 7 test bugs should be filed against "devel", not against test1/2/3. This
isn't obvious, I know. Moving this report so it isn't lost.

This is a bulk message -- I apologize if this was actually meant to be targeted
against a different release. If so, please fix or let me know. Thanks.
Comment 4 Gian Paolo Mureddu 2007-04-10 14:34:56 EDT
Yes, it is not obvious as Bugzilla has not reflected the changes in Fedora 7
(like the merger of Core and Extras and some bugs filed for components such as
AbiWord have to be directed to Extras [why is this so beats me]), all the same,
this report was targetted for Fedora 7 devel, and thanks for the clarification.
Comment 5 Michael Forrest 2007-07-11 08:35:17 EDT
There appears to be a regression for me also for 3D rendering on Fedora 7's
via driver.

The glxgears window is missplaced, and if the window is moved from the top
left corner (defauly placement from metacity), the misplacement increases
so that if the window is moved down 100 picels, the 2D window of glxgears
moves down ~200 pixels. Same for howizontal.

This makes 3D totally unuable for me. I will attach lspci -vv output.

lspci from Fedora 6

Note that 3D works fine with FC6 using this hardware (I dual boot to either 
6 or 7).
Comment 7 Matěj Cepl 2007-07-11 10:01:04 EDT
Both to reporter and Michael:

Thanks for the bug report.  We have reviewed the information you have provided
above, and there is some additional information we require that will be helpful
in our diagnosis of this issue.

Please attach your X server config file (/etc/X11/xorg.conf) and X server log
file (/var/log/Xorg.*.log) to the bug report as individual uncompressed file
attachments using the bugzilla file attachment link below.

Could you please also try to run without any /etc/X11/xorg.conf whatsoever and
let X11 autodetect your display and video card? Attach to this bug
/var/log/Xorg.0.log from this attempt as well, please.

We will review this issue again once you've had a chance to attach this information.

Thanks in advance.

I have attached the requested information.

I will also attch the lspci from Fedora 7, and two screen shots illustrraing:

- glxgears in its initial position
- glxgears after moving the window framee about 100 pixels down,
  showing that the misplacement has increased compared to the previous
  position

Comment 15 Michael Forrest 2007-07-14 01:54:29 EDT
Did a 'yum update' today.

Now, the misplacement problem has disappeared for me.

Can you confirm. glx-maintainers, whether or not the bugfix in:

glx-utils.i386 6.5.2-13.fc7

Could have corrected the problem we have documented here?

I will not move this bug to fixed, since I am not the original reporter.
Comment 16 Adam Jackson 2007-07-27 17:06:47 EDT
Pretty sure this was fixed by Mesa update.  Reopen if I'm wrong.
