Fedora :: NVidia And Compiz Installed And Working But Screen Doesn't Refresh Correctly?

What it does is, if you do something to change anything on the screen, for example, highlighting text, or switching from one tab/menu in an application to another. The screen doesn't show the change. The only way to SEE the change is to do something else to the screen, like grabbing and moving the application around, or scrolling the page of a website, etc. If you don't do that, you won't see what's really on the screen, but rather what WAS on the screen.

Another example:

*) say you have an application open with 3 tabs: tab1, tab2, and tab3.
*) Switch from tab1 to tab2 and you see no change on the screen.
*) Switch from tab2 to tab3 and you see tab 2 on the screen, NOT tab 3.
*) Switch from tab3 to tab 2 and you see tab3 on the screen, and NOT tab2.

Or, if you're typing in this box to make a post, and you hit ctrl+a to select all, you see no change. If you click in the box to deselect all, then it looks like you've selected all text still. The only way to see what's currently on the screen is to scroll the text box or page just a bit, or, if you're using an application, then you'd have to move it around on the screen a bit.

As i've said, the nVidia drivers are installed and working, as well as compiz, etc.

Code:
[=v=]$ lspci
00:00.0 Host bridge: ATI Technologies Inc RD890 Northbridge only single slot PCI-e GFX Hydra part (rev 02)
00:02.0 PCI bridge: ATI Technologies Inc RD890 PCI to PCI bridge (PCI express gpp port B)

[Code]....

Also, i did BOTH the dracut thing, and the extra kernel paramter in the grub.conf. So, nouveau is blacklisted. Oddly enough though, i do NOT have this problem when using the nouveau driver...

Also, fwiw, i think that i should mention that i'm not using the "Desktop Settings > Enable Desktop Effects" method, because i always seem to have problems with getting certain features to work, like the background for the cube skydome, etc. How i do it is that i install a package called compiz-manager, and i have it set to run at session start. This makes all of the compiz features work fine. One thing that i've noticed though, is that on my other workstation, i haven't set that up yet, and it seems that is is NOT having the same issue. While compiz-manager was running, i tried to use the "desktop settings" method, and it crapped out and reverted back to the old school desktop. I then tried it again, and it reloaded compiz, and there is no screen update issues now. So it seems that you have to have both of them running in order to get all of the compiz options to work, and not have the screen refresh issue?
