Desktop effects causes titlebar anomaly

A screenshot of the bug is attached.

Here is another screenshot of the bug.

confirming because I have the same problem. i use an nvidia 6100 GeForce go card. for me it seems like it only happens on maximized windows.

I have also observed that this problem only happens with maximized windows; however, it seems like when I have a restored window, I occasionally am logged off when I click minimize button

I will try running without desktop effects and see if this latest problem continues to occur

The problem does not appear to occur when desktop effects are turned off.

I'd like to confirm that this bug still exists. I'm using a nvidia 6200 on intrepid beta. Think I'm using 177.76. Happens not just on maximised windows, and very regularly. Happy to provide more information if someone can let me know what would be useful.

I can confirm that this bug is still in effect in Intrepid with the latest updates as of this morning (Nov 7th). I'm running a 7600GT with the proprietary drivers. The bug happens when I have Visual Effects set to Normal and when I use my mouse to hover over the Min/Max/Close/leftside icons in the window titlebar.

The bug ONLY occurs if the window is currently in focus, and ONLY occurs with the mouse cursor over the titlebar buttons. If it is not in focus, then no amount of hovering will create artifacts.

If I mouse over the buttons and get the artifacts, then I can usually get back to normal by hovering again, and then moving the cursor away from the titlebar.

Another similar screenshot.

Same problem here. Just installed 8.10 on machine with Geforce 7600GT. Enabled the recommended version 177 driver and Extra desktop effects (the 3rd option).

i have the same problem with a Geforce 6100. I've also noticed that it only happens on the Human theme though.

I also have this problem with my 7600gt. I can confirm that choosing another theme than human or human-clearlooks fixes this (I'm currently using clearlooks). Going by the other posts this problem only affects Nvida GeForce 6 and 7 series. According to Wikipedia GeForce 7 is an "upgrade" of GeForce 6: "The design was a refined version of GeForce 6, with the major improvements being a widened pipeline and an increase in clock speed." (http://en.wikipedia.org/wiki/GeForce) GeForce 8 on the other hand was a brand new arcitechture, this would explain why this only seems to happen with 6 and 7.

I'm running 8.04 with an Nvidia GeForce FX 5500. The bug is definitely present with desktop effects fully enabled while using the Human theme. (Thanks to BasherBob for the theme tip). I never had this problem with my old ATI Radeon 7000 PCI card, but must admit it didn't keep up very well under a full compiz press.
