I had an old machine running some ancient version of Fedora (13 or something, I think). All was good. But obviously obsolete and probably insecure. So I upgraded to Fedora 20 before Christmas. I typically use fvwm. However, when I move windows, an image of the window in its previous position remains. See the following screenshot: http://pics.astradyne.co.uk/ref/150101--fvwm.png Note that there is only one terminal open here. The rest are ghost images. It doesn't do this if I use GNOME or KDE. I initially thought that it might be an fvwm problem. But I can replicate it using icewm as well. There are two ways to start the window manager - via the session type dropdown box, or via a user script (~/.Xclients). Playing around with a few options, I get the following results: Starting from session dropdown: fvwm - broken icewm - working KDE - working GNOME - working XFCE - working Starting from ~/.Xclients: fvwm - broken icewm - broken xfwm4 - broken mutter - working kwin - working This is with Intel graphics: macbeth:~# lspci | fgrep VGA 00:02.0 VGA compatible controller: Intel Corporation 4 Series Chipset Integrated Graphics Controller (rev 03) I tried compiling a new version of fvwm from source, but that showed the same problem. icewm and xfwm4 are intriguing in that they're broken from ~/.Xclients but working from the session dropdown. Any ideas?
