When moving a Window to another Workspace (that means: drag&drop, changing the workspace when the mouse pointer reaches the screen edge), KWin crashes and shows the "Problem report"-window. This only happens with compositing enabled. Reproducible: Always Steps to Reproduce: 1. Terminal: kwin_x11 --replace 2. Grab Terminal-Window and move to egde of screen to switch workspace Actual Results: 1. kwin crashes 2. crash report assistent appears 3. kwin restarts automatically 4. window is on new workspace Expected Results: window appears on new workspace without a crash :) System: Tanglu (Debian 8-based) Desktop: XFCE 4.10 with KWin instead of xfwm4. Kernel: 4.0.0-2-686-pae. lspci -nnk: 00:02.0 VGA compatible controller [0300]: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller [8086:2a42] (rev 07) Subsystem: Hewlett-Packard Company Device [103c:30dd] Kernel driver in use: i915 kwin-dbg and qtbase5-dbg are installed, but the crash report assistent is still missing them. Terminal-Output of kwin--replace until crash: http://pastebin.com/W9sY0FWM Backtrace: http://pastebin.com/TWmfV9DK
