When using "static application switcher" (or "application switcher"), maximized windows have a preview that's ok.
Non-maximized windows without transparency, are painted 100% black in the preview.
Non-maximized windows with transparency, are painted 100% transparent (blank).
I'm not using any window decorator (I feel this might be relevant for some reason).
I'm not sure what info may be relevant; i'm attaching my compiz configuration. |

I just managed to get my hands on another computer that was already running compiz 0.9.7.4, and did not have this issue. After some testing, I discovered that disabling the "window decoration" plugin causes this issue; if it's disabled, window previews in the "application switcher" are corrupt for some reason.
The computer I'm using does not have this plugin enabled, or any working window decorator either.
IIRC a similar issue was present in compiz 0.9.2 or 0.9.4. |

When a window decorator is not in use, both the "application switcher" and "static application switcher" show corrupt previews (blank for windows with transparency; black for non-maximized windows, ok for the rest).
After two or three uses (use alt-tab to change window, let the dialog fade, then do it again) the screen freezes.
I've tested this on three machines:
The first machine (laptop) has an Intel video card, and the screen turns off, and /var/log/kernel.log shows the attached errors. A full power cycle in required to have the display work again (not even restaring via SSH works; the screen remains off).
The other computers have nvidia video, and simply freeze. I can SSH into it, kill compiz, and restart it [compiz] and it goes on running fine (except for the initial issue).
In this case, compiz spits out the following warning every time I alt-tab: "compiz (core) - Warn: failed to receive ConfigureNotify event on 0x600293".
I've just now discovered that enabling the "Show icon only" option for the "Static Application Switcher" plugin avoids these crashes/fixes; though an alt-tab with no preview is really sad (but a workaround for the meantime, nonetheless).
I can provide any other information that may be needed, or test any fixes/alternate builds/etc. |

When no window decorator is used, *application switcher shows corrupt previews and eventually dies. |
