Created attachment 117704 [details] LibreOffice 4.0 text In LibreOffice 5.0, all the text is blurry on my HiDPI Linux box, and looks worse than the previous versions. I'm including a screenshot of 4.4.5 and 5.0 for comparison. I've disabled both options in the UI for anti-aliasing and have the UI scaling at 100%.

I found out that this bug is an issue only for distros that use the LibreOffice Gtk 3 support. Arch enabled it in their new release. I filed a bug asking them to go back to Gtk2: https://bugs.archlinux.org/task/45916?project=1&opened=16914 I still think this bug should be fixed, but the priority depends on how many distros are using the Gtk 3 support.
This is fixed in master with [1]. Backport to 5-0 [2]. [1]: http://cgit.freedesktop.org/libreoffice/core/commit/?id=2a19bb85cbe83aa031871a3689b9ff03629da548 [2]: https://gerrit.libreoffice.org/#/c/17553/
Verified it is gone with 5.0.1.
