Big black horizontal lines in some games!

[khr]

When i play some games, there blinks big black horizontal lines on the screen. Its very irritating and painful to my eyes... This applies to some games, here is a list of all the games its happening to:

Neverputt, Neverball, Xmoto, OpenArena, World of Padman, Supertuxkart, Chronium, and probably many more that i haven't tried...

The connection between all of these games is that they are 3D.
(Except Xmoto, its probably there because its using openGL, i think.)

To explain the big black horizontal lines easier, they look like old movies.
You know with those gigantic film rolls? Kinda like that, only worse...

Personally i think the problem is either a wrong horizontal sync or wrong refresh rate...

Also, i didn't have this problem before i followed this guide:
http://wiki.cchtml.com/index.php/Ubuntu_Hardy_Installation_Guide
(Manual Method)
Before i followed this guide, every 3D/openGL game was unplayable since it lagged so much. But after i followed this guide all the 3D/openGL games worked 100% lag-free, except the black horizontal lines...

So, please help me with this!!!

PS:
Just in case you would've wanted it, here is my true horizontal sync and vertical refresh rates:
Horizontal Sync: 54.01 kHz
Vertical Refresh: 60/65 Hz
(I'm not really sure if the vertical refresh rate is 60 or 65 Hz...)

Please help!!!
I'm desperate!!
I don't want to go back to Vista!!!

I'm going to go and watch a movie so you won't be seeing me in the next 2-4 hours...

Is libglide3 installed? When I was solving my 3d acceleration problem I noticed black horizontal bars when playing Super Tuxcart. When I installed libglide3 they went away. I don't know if this will help but hopefully it does.

you need to either disable desktop effects or change your monitors refresh rate in xorg.conf. Try the suggestion above mine first ^^ touche

I installed libglide3 with synaptic, sadly, it didn't help... :(
Thanks for posting!

I really don't want to disable compiz, so i'll try to change my monitor refresh rate in xorg.conf... But I'm not sure what to change...

Here is my xorg.conf:


# xorg.conf (X.Org X Window System server configuration file)
#
# This file was generated by dexconf, the Debian X Configuration tool, using
# values from the debconf database.
#
# Edit this file with caution, and see the xorg.conf manual page.
# (Type "man xorg.conf" at the shell prompt.)
#
# This file is automatically updated on xserver-xorg package upgrades *only*
# if it has not been modified since the last upgrade of the xserver-xorg
# package.

# If you have edited this file but would like it to be automatically updated
# again, run the following command:
# sudo dpkg-reconfigure -phigh xserver-xorg

What should i change?
You probably won't see more before 2-4 hours, going to watch movie.

[khr]

Do i actually have any other options besides editing the xorg.conf file?

[khr]

I've now edited the xorg.conf file and changed the horizSync and vertRefresh to the correct value. It had no effect on my issues...
I also reinstalled the games, but the problem is still there.

Please help!

PS:
Does ATi provide support for ATi in Ubuntu?
