I am running VIM 7.4 on Ubuntu 14.04.4 and noticed that this problem only appeared *after* I switched to an AMD Radeon 7770 graphics card. Previously, with my Nvidia graphics card this problem did not exist.
I am running the fglrx-updates proprietary driver provided by the built- in "Additional drivers" tool (2:15.201-0ubuntu0.14.04.1). -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to vim in Ubuntu. https://bugs.launchpad.net/bugs/320700 Title: gvim rendering is slow Status in vim package in Ubuntu: Confirmed Bug description: Binary package hint: vim Rendering in gvim is very slow compared to previous Ubuntu releases. It's usable, but takes patience. I'm using vim/gvim 7.1.314-3ubuntu3.1 on Ubuntu 8.10. Others have reported this same issue on a thread from the vim mailing list. Many solutions have been tried w/o success: http://groups.google.com/group/vim_use/browse_thread/thread/dd1d8d9a799adf4a From the thread, someone provided this benchmark script: -- -- -- " Benchmark vim's redrawing speed let i = 0 while i < 2000 1 redraw $ redraw let i = i + 1 endwhile qa! -- -- -- I've run it with /etc/init.d/README as an input file (just to pick something consistent across Ubuntu machines): $ time vim -u NONE -U NONE -S test-redraw-speed.vim /etc/init.d/README real 0m5.407s user 0m0.568s sys 0m0.048s $ time gvim -u NONE -U NONE -f -S test-redraw-speed.vim /etc/init.d/README real 3m27.614s user 0m11.685s sys 0m0.312s As you can see gvim is almost 40x slower then vim (running in gnome- terminal). You'd expect gvim to be slower then vim, but not by this much. Note, from the thread, not all users experience this huge difference. Some only report 2-3x slowdown, which I'd be very happy with at this point :) I'm using the radeon X11 driver (open source) on a ThinkPad T42p, and do _not_ experience slow rendering in other apps (for example, gedit).
