Version: (using Devel) OS: Linux Installed from: Compiled sources Using kde4-nightly, latest build, on Ubuntu 8.10. When resizing the default panel, the bottom half of screen becomes black and covers all windows. The only way to remove it is restart plasma. See attached screenshot.
Created attachment 29791 [details] Plasma after resizing panel.
After resizing tried to remove the bottom panel and got crash: Programma: Plasma darbvirsma (plasma), signāls SIGSEGV [Current thread is 0 (LWP 17163)] Thread 3 (Thread 0xa95d3b90 (LWP 17164)): #0 0xb8056430 in __kernel_vsyscall () #1 0xb68ee075 in pthread_cond_wait@@GLIBC_2.3.2 () from /lib/tls/i686/cmov/libpthread.so.0 #2 0xb6953b6e in QWaitCondition::wait () from /opt/project-neon/lib/libQtCore.so.4 #3 0xb7ac3802 in ??

Oh, wrong about the covering of windows. The blackness covers only plasma widgets. Also this can be triggered by adding empty panel and resizing it.
