I'm running Gvim 704 on Windows 7 Ultimate x64. Sometimes for some unapparent reason I get these blue dot artifacts:
I'm very minimalist when it comes to plugins, I only use pathogen, ctrlp, nerdcommenter, tabular, vim-scroll-smooth and vim-surround. I also have a dll that enables me to go fullscreen via F11.
If I do any activity like changing windows (give focus to another window and refocus on vim again), close/reopen the vim buffer/window, toggle fullscreen etc the artifacts go away. It updates its position in the screen as I scroll up/down.
Here's my vimrc:
behave mswin
source $VIMRUNTIME/mswin.vim
let $PATH .= ';C:\Windows\SysWOW64'

I never had these issues before but I vaguely remember starting to have them around the time I added the ilnes:
set ttyscroll=0
set nocursorline
set nocursorcolumn
syntax sync minlines=256
I'm not exactly sure they're related but I do remember adding them was an attempt to solve the rendering/artifacts problems. The artifacts don't happen in a replicate-able manner so even if I were to disable those options I might not see any immediately but eventually do.
Does anyone have any idea what could be causing this and how to get rid of it?
