Description of problem: When I use Alt-Tab to select a new window, the new window is completely black until I release the Alt key. This means that if I have a bunch of, say, browser windows, I can't see the contents of the window until I select it. If I'm cycling through the windows, only the one I'm about to select is black - the others all appear normal. Version-Release number of selected component (if applicable): metacity-2.16.0-8.el5 How reproducible: Always. Steps to Reproduce: 1. Hold Alt 2. Press Tab once or more 3. Actual results: Windows are successively selected, brought to the front, but filled with black Expected results: The selected window should show its current contents Additional info: This is the only Linux installation I've seen where this doesn't work. I have the nvidia driver 169.09 installed. One other note is that the SHAPE extension is currently disabled (the installation process did this).
The shape extension is required for the correct operation of Metacity - the black border used to highlight the position of the selected window is a window shaped to be a thin frame using the shape extension. Without the shape extension, the effect will be as you describe - a large black rectangle. I'm not sure how you ended up with the SHAPE extension disabled - it sounds like perhaps it was related to the installation of the NVIDIA driver in some way. If you believe that there is a way of installing RHEL that ends up with the SHAPE extension configured off, feel free to describe the installation process you followed and reopen this bug and I'll try to reassign it appropriately.
