------- Additional comments from tjfraz...@openoffice.org Sun Apr 19 01:42:09 +0000 2009 ------- History: first noticed in 3.0, but I never used odd zooms before the lovely new two-page displays in 3.0, so no idea how old the problem really is. Present in 3.0.1 and 3.1rc1. Problem: Using PageUp and PageDown keys, with odd zoom factors, shows garbaged lines at bottom or top edge of display. With PageDown, error shows at bottom; PageUp travel shows at top. This is a little fiddly to reproduce, since it also depends on the display window size. The window must not be exactly right, vertically, to display an exact number of lines. OTOH, I can reproduce it on any sizeable document, and once found, it is 100% reproducible both in place, and with the exact sequence of keystrokes. See the screen-shots (TBA) for the kind of garbage to look for. The document in the shots is from the specs library on the OO.o site, "Custom Document Properties.odt", but any conveniently long doc will do. 1) Open long doc. 2) Set zoom factor to 105% by clicking on the circled "+" icon near the right end of the status bar, next to the zoom factor box. 3) Start at the beginning (Ctrl + Home) and press PageDown key repeatedly until garbage appears at bottom of window. (Alternatively, start at end (Ctrl + End) and press PageUp; garbage appears at top of window.) This may take more than a dozen key-presses. Note in the screen-shot that I got all the way to page 6 before it broke. If no garbage, adjust the vertical window size a little, and retry from Step 3. The key factor is that the set of lines in the window has to "creep" a little, in terms of the vertical white space at top and bottom. Eventually, Page key and creep will hit the critical point. 4) Once the garbage appears, the same number of key-presses from the same starting point will reproduce it. Also, paging the other direction, and back again, will reproduce. Garbage may be scrolled for inspection. Problem does not occur with scrolling, or Next Page / Previous Page arrow controls. I /think/ it occurs with other jump-type positioning, such as jumping to a bookmark. Because the workaround is so simple -- anything that forces repaint -- I have set P4 priority. But this is sure one ugly nuisance. /tj/ --------------------------------------------------------------------- Please do not reply to this automatically generated notification from Issue Tracker.
