This is a regression with Openoffice. Browsing the file https://bugs.freedesktop.org/attachment.cgi?id=52632 is much more slower than with OpenOffice 3.3.0. About 10s with LO and less than 1s with OOo. Note that Acceleration in Option is activated in LO and not selectable in OOo. Debian 6.
not reproducible with 3.5.0beta2 - document loads instantly and also scrolling doesn't cause any noteworthy delays → worksforme
Reproducible with 3.5.1 Final. About 5 sec with LO (worst without acceleration) to scrolling. Much faster in OOo 3.3.0 (less than 1 s). Debian 6.0.3 and testing. Radeon video card. Reopen.
Reproducible with LO 3.6.0 final.
The display speed is now normal. LO 4.3.1.2. Debian 7.6 with kernel 3.16.1.
