Package: vim-gtk Version: 2:7.4.488-4 Severity: important Dear Maintainer,
I'm using gVim on a fresh sid install. When I open up a file and scroll around (usually using the PgUp and PgDn keys), I'll often see large areas of text missing from the screen. What I'm seeing is very similar to what's in the linked video in this superuser question: http://superuser.com/questions/343599 /gvim-redraw-failure If I navigate through the empty area with the arrow keys, each character will display as the cursor goes over it, one at a time. Hitting PgUp or PgDn again will usually restore the text, but will often result in a different region becoming blank. `:redraw`, `:redraw!` and ^L exhibit the same behavior. Alt-Tabbing out and back into the window always redraws everything correctly. Trying to figure out what was wrong, I ran strace on the gvim process. To my surprise, I could not reproduce the issue while strace was running! I then realized it was because strace was frequently outputting to a terminal behind gVim, and evidently was forcing rapid screen redraws. So that seems to be a workaround (but certainly not a good one). I don't know much about low-level display stuff, so I'm not sure whether this is a gVim problem or something else. My terminal (terminator) does not exhibit anything like this, and neither does regular vim. I'm running lightdm and openbox. I'm also running xcompmgr, but the issue persists whether or not xcompmgr is running. I should also note that I'm running on a virtual machine (VMware tools). I say that because I have a system running sid at home that does not have this problem. Let me know if you have any ideas. Thanks!
