I started using gVim a few weeks ago. From early on, I noticed however some strange resizing of the complete gVim window when I perform certain actions. I think it is related to my use of Windows Aero Snap (on a Windows 7 x64 system).

Steps to reproduce (with an empty .vimrc file, and my vimfiles folder renamed):

  1. I open gvim
  2. I put my gvim window to the left side of my monitor with (a few taps on) win+left arrow
  3. I create a new tab using :tabe

Result: gVim repositions itself somwehere else on the screen. So I have to reposition it using win+left arrow. Very annoying.

I have it with other tab and window actions as well, like: :vnew, C-W o, ...

Anybody any tips on why this is happening, and what i can do to fix it? I've already emptied my .vimrc file and temporarily renamed my ~/vimfiles folder to rule out the interference of any plugin.

Edit: Following Matthew's reply, and the info on :help bugs, I've send a bug report (this post actually) to bugs@vim.org
