Well, I managed to have the bug produced after I started lyx from terminal in debugging mode. When the GUI froze, the terminal was full of errors of this kind: X Error: BadPixmap (invalid Pixmap parameter) 4 Major opcode: 54 (X_FreePixmap) Resource id: 0x4d862c9 X Error: RenderBadPicture (invalid Picture parameter) 182 Extension: 156 (RENDER) Minor opcode: 7 (RenderFreePicture) Resource id: 0x4d867c0 X Error: BadPixmap (invalid Pixmap parameter) 4 Major opcode: 54 (X_FreePixmap) Resource id: 0x4d867bf X Error: RenderBadPicture (invalid Picture parameter) 182 Extension: 156 (RENDER) Minor opcode: 7 (RenderFreePicture) Resource id: 0x4d86ca0 X Error: BadPixmap (invalid Pixmap parameter) 4 Major opcode: 54 (X_FreePixmap) Resource id: 0x4d86c9f When I quit the application with CTRL-Q, I found this: GuiClipboard.cpp(418): Qt Clipboard changed.
