Reproduced on 12.10 with emacs-snapshot. Also on 12.04 LTS with emacs24.
I don't have any special PDF viewers installed, just the stock Evince.
1. Open PDF file in Emacs
2. Try normal user inputs (mouse scroll, C-p, C-n, n, p, etc.)
3. Expected: UI responds immediately as other PDF viewers do
3. Actual: There are delays between 0.5 to 2 seconds until the UI updates. During the delay, Emacs is frozen.
I can't reproduce this with the Emacs 23 provided by Canonical (responsive DocView). However, I *can* repro with Emacs 24 provided by Canonical. Both on Quantal. |

Reproduced on 12.10 with emacs-snapshot. Also on 12.04 LTS with emacs24 (both from PPA and from canonical).

1. Launch emacs with "emacs -Q"
2. Open a PDF that has pages you can scroll
3. Scroll around (should be responsive)
4. Turn on `M-x global-linum-mode`
5. Ensure the global-linum-mode is enabled and now scroll around. There should be a noticeable lag that makes it really difficult to use. |
