computer video screen problem...screen splits, doesn't update...Xgl/Compiz-Fusion/NVidia problem??

[Will McCreight]

I have been using Gnucash for some time now for personal use of
checkbook features, and I like it a lot. However, I am having difficulty
with the video screen not updating properly and I think it has to do
with NVidia/Xgl/Compiz issues which then present themselves in the
Gnucash window while it is up. I am running OpenSUSE 10.2, newest Nvidia
drivers, Gnucash 2.2.0, Compiz-Fusion newest version. This problem first
arose when I updated drivers for NVidia and moved from Beryl to
Compiz-Fusion, and I have not had this issue with any other program
(other than it "breaking MythTV's ability to play back a recording",
which I have been able to fix with an environmental variable which
apparently turns off Xgl for that "session" of MythTV).

When I open Gnucash, the left hand side of the window is correct, but
the right half of the window is black. When I click on the account tabs,
often the lower portion of the screen (on both left and right sides)
which displays the check register does not change, still shows the old
account info. When I enter a check and it now jumps up a line to allow
me to enter another check, there is a copy of the old data (a duplicate)
in the "new" line position until I click into one of its fields, and
then the line clears to blank to allow me to enter new data. Often the
left-right screen split happens, where one side of the check register
only updates to, say, the new account, while the other half still shows
the old account's data.

I have been able to use Gnucash despite these difficulties, but it is at
minimum annoying, and at most, worrisome that I may lose data, or at
least confuse data.

I think this is an issue with Gnucash and/or Compiz and/or the NVidia
driver not updating the screen properly. It has not crashed my X session
the way MythTV did for a while, before I discovered the NO_XV
environmental variable which MythTV apparently uses to turn off Xgl for
its session...might there be a similar switch or environmental variable
which Gnucash can use in my situation?

I have been searching the internet for a similar complaint to mine, but
so far have found none.  Any suggestions?

Thanx in advance,
Will
