<pre>Description:
Since version 6.3.6, a presentation containing basic animation effects (appear
on click) is displayed correctly only in forward direction (objects show up
sequentially in response to a mouse click or a cursor down-right, page-down key
press). When presentation is scrolled back (cursor up-left, page-up key),
however, objects do not disappear one by one in reverse order as expected, but
rather in an unpredictable sequence and often in pairs. When the presentation
direction is reversed again (forward), some objects do not reappear, unless
reversal has occurred at the beginning of a slide. LO versions <= 6.3.2 are
seemingly not affect by this bug, although thin white strips superimposed to
objects occasionally appear on scrolling back.
Steps to Reproduce:
1. Create a one-slide new presentation, create/insert a few objects (any type:
text boxes, images, etc.) and enable "appear on click" animation effect on
them.
2. Start presentation, click mouse or press right, down cursor key to make
objects show up.
3. When the last object has appeared, press left, up cursor or page-up key to
rewind presentation.
Actual Results:
At point 3 (presentation rewind) objects disappear in erratic sequence and
often in pairs.
Expected Results:
At point 3 (presentation rewind) objects should disappear one by one in reverse
order of their creation.
Reproducible: Always
User Profile Reset: Yes
OpenGL enabled: Yes
