Yes, it was just empty. Well, filled with memory noise. I've added a background rectangle, set layers, and it is working now. But I've problems using transparency. I can set the window shaped, but no alpha and transparency. I've tried it with the gl_x11 and software_x11 engine, but both fail to draw a half-transparent background. I even tried a .png with a gradient from red to transparent, but no luck. Using gl_x11 fails at all and logs messages about a missing or wrong input handler/method/whatsoever. As soon as I set alpha or transparency. But a glxinfo says that direct rendering is enabled. Did I miss something setting up OpenGL? Is there any X module that needs to be setup to get transparency? Another thing is that, if I use gl_x11 without transparency at all, the actual cpu load is at ~40%. software_x11 will use just ~8%. I thought that it should be the opposite. This happens on two different computers.
