The problem can often be reproduced with something like: for i in `seq 200`; do xterm -geometry 80x24+0+0 -e true & done
There may remain several windows. When I do an ident on one of them, all of them disappear. I initially thought that FvwmIconMan could be a cause (since it is new in my config), but this bug is reproducible without it. -- Vincent Lefèvre <vinc...@vinc17.net> - Web: <https://www.vinc17.net/> 100% accessible validated (X)HTML - Blog: <https://www.vinc17.net/blog/> Work: CR INRIA - computer arithmetic / AriC project (LIP, ENS-Lyon)
