when desktop-effects enabled, apps requiring sudo permissions not showingup correctly

Binary package hint: desktop-effects

This is an up-to-date fiesty system, including the compiz-extras.
But I am seeing this issue for a while now.

when I enable desktop-effects, all normal apps work fine. but applications requiring to enter password (synaptic / login manager etc) behave strangely.

1. The password prompt app (gksudo ?) has the password textbox with junk password. You don't see echos (with * or filled circle) of the characters. The textbox stays blank. But if I click on OK, the application comesup fine on entering correct password.

2. The progressbars don't indicate status correctly. It stays at 0%, even though actual processing is going on. The window just closes after everything is done. For example synaptic reload from repos, just shows 0% complete till the end.

3. The administration menu (after preferences) doen't highlight entries where I kept mouse pointer. Popups showup describing the app, however. This is not the case for preferences menu however, highlighting works however.

I forgot to mention that this is on Acer travelmate 4150 laptop, intel 915 video card.

I can confirm the same behavior on an HP/Compaq nc6220, again using Intel i915 video.

The password field issues are an inconvenience at most but the SERIOUS problem is the terminal window suffers from the same problem - terminal windows open before turning on desktop effects are ok but any subsequent terminal windows are blank.

After some searching I found a post specifically talking about compiz on the i915... Add this option to your Xorg.conf in the Device section for your Intel video card:

 Option "XAANoOffscreenPixmaps"

Seems to have fixed issues for me - terminal windows now draw properly, password fields now display stars as expected, gksu works properly, etc.

I'll give it a bit more time before I call this the definite fix as some of the above problems didn't happen with me initially under Herd 5.

Definitely fixed it!! Desktop effects working perfectly... Very nice!
