to reproduce the bug, I have to grab the window with the mouse and (while keeping the left button pressed) move it to any edge of the screen until the cursor touch the edge. In that moment, the pc gets frozen. Please provide the output of qdbus org.kde.KWin /KWin supportInformation If you are able please gdb into the hung KWin and provide a backyard of all threads. Of course I don't see this problem... I took this while I was using wayland https://paste.kde.org/peslqxmiq you are using the QPainter compositor? Why? Copy from paste (pastes expire):

The problem indeed was the compositing, I was using xrender (since on X11 opengl 2.0 & 3.1 has given me some issues, so on my case xrender is the best option there), but I switched to OpenGL 3.1 and now this specific bug is fixed. Here is the new output, now with opengl 3.1 http://pastebin.com/kQrGD6Wf In other words, xrender is just not compatible with wayland. Good! It shouldn't freeze nevertheless, but it kind of makes sense. And yes Xrender (having X in it's name) doesn't work and doesn't make sense on Wayland. |
