This bug happens to me ALL the time. At LEAST 30 times per day. I average 40 new windows per hour! (of course I close a lot too). I always mostly have 15+ windows open. Mostly...
My Panels are both auto-hidden, and expand-disabled (variable width). Was using Intrepid x64, Compiz Fusion, Cube Plugin (+ Rotate Cube) (3-face) - ALWAYS had problems Then upgraded to Jaunty x64, Compiz Fusion, Cube Plugin (+ Rotate Cube) (3-face) - ALWAYS had problems Then Jaunty x64, Compiz Fusion, Desktop Wall, & Expo Plugin (4-Desks) - ALWAYS have problems This *only* occurs when switching view points (desktops). I've noticed, it takes about half a second for the windows (on the panel of the desktop I just switched to), to be 'rendered' or displayed. I can see this as it takes about half a second for the 1px visible line (of the 'off-screen' hidden panel) to resize itself to the number of windows open on the desktop I switch to. So, i've noticed that to prevent the bug from occuring, I MUST wait that half a second BEFORE accessing my panel (i.e. making it slide up from auto-hide). This way, the error almost NEVER occurs. If however I switch desktops like a crazy person (I'm always flying), & then try to access/pull up the panel from auto-hide almost immediately, or if I'm already moused on the panel (it's visible) when I make the switch to another desktop, the error occurs 80% of the time! So, it's VERY Reproduce-able! My silly workaround is a combination of the half-second wait as explained above, & as I always have Amarok running, I press Ctrl+P to bring up Amarok, then wait half a second to render the new panel, then Ctrl+P again to make Amarok disappear, and a final half-second wait to render a new panel again. This trick works 98% of the time! Again, controlled manipulation of the bug. *** I just made a screenshot of this bug on demand - it took me less than 2 SECONDS to reproduce! (mouse was over panel, changed desktop with keyboard, then INSTANTLY changed back to the same desktop - & the panel was never refreshed *** *** Also note, that in order to cover up sensitive data on my Desktop (I'm paranoid), I made 4 attempts to create the perfect screenshot! EACH time I could instantly reproduce this at will, as I know 100% how to make it happen. So yeah - it happens a lot *** So, it's REAL! I've given all the instructions to reproduce, & play with the bug. Please help us with our infestation!
