This is current/amd64, making a screenshot with xwd > file.xwd
X Error of failed request: BadColor (invalid Colormap parameter) Major opcode of failed request: 91 (X_QueryColors) Resource id in failed request: 0x0 Serial number of failed request: 114 Current serial number in output stream: 114 That's a window dump of chrome. A window dump of xterm or mupdf works just fine. I am not sure where the error is. Does chrome use some Colormap that xwd cannot cope with? Does it make a difference to xwd which window it is dumping? Jan
