Hi, i use tpope/vim-obsession for saving and loading vim session files. After starting vim on a session file like vim -S .Session.vim, dwm.vim seems to respect the sizes of the windows, yet the windows contain different buffers than before. In other words: it seems to me, that one of the buffers gets moved to the master pane and hereby rearranges all buffer locations, just like Ctrl-space.
If i move the desired window to the master pane, the layout size isn't respected any more - it seems to me like a Ctrl-W = is done.
