Apache OpenOffice (AOO) Bugzilla – Issue 94627
line redraw lagging after assigning new font height
Last modified: 2013-08-07 14:38:26 UTC
After changing the font size of a paragraph, Writer adjusts the position of all preceeding paragraphs. But sometimes some lines seem to be misaligned and Writer moves them up/down a pixel. These Lines are moved one by one with a delay of ~2 seconds between each line. Here is an animated gif showing the bug: http://www.pfadwaechter.de/openoffice/ openoffice_bug.gif (document used for animation: http://www.pfadwaechter.de/ openoffice/test.odt) The redrawing continues even if the user modifies content below the changed paragraph. This is very distracting since the eye is "trained" to register movement outside of its focus. I gave this bug a priority of 3 because i think that it is more than just a cosmetic issue. Another interesting point is that this bug occurs in all versions of OpenOffice since 1.x. Reproduction of the bug: - open "test.odt" - select any paragraph (preferably the first one) - change font size to 13 - click somewhere else in the document (to deselect the paragraph) - watch ... i could reproduce the bug with the provided document very easily, but it does not always occur all the time in all documents.

MRU->FME: this is a quite funny effect. Use the attached document. Select one of the first paragraphs and assign new font height of 13 pt. The click into text to de-select. Watch now how every ~2 secs a line in the text will be redrawn.
