Description Unknown 2002-09-21 18:15:11 UTC
The tooltip that appears when the counterweight is grabbed by the mouse in order
to scroll the document, causes corruption of the screen display when scrolling
that reamins after scrolling is complete.

An image is provided at the URL above, which points to a .png file showing the
corruption.  I couldn't capture the tooltip, but when the document contains
sections, then the scrolling tooltip is very wide.  When it extends into the
text display area, the display becomes corrupted.  This problem has been
observed on several machines with different video cards.  The Ctrl-Shift-R
command fixes it, thus it appears to be a failure to refresh the screen once
more after scrolling is complete.

Suse Linux 7.3, OO.org 1.0.1

Here's a link again to the .png for convenience:

Hmm, I thought I was attaching a file to issue 6069, but it wound up
here.  It appears that this is related to 6069, but not sure.  This
may be a separate bug, with similar manifestations.

Anyway, the newly attached file demonstrates screen corruption when
scrolling, and this problem occurs in 1.0.2.  There are two aspects to
this corruption:  First, the display becomes corrupted when the
tooltip associated with the vertical scrollbar overwrites the main
display.  To notice this effect, scroll through the page 2 of
attachment ID=4674.  Usually, when scrolling down, the problem doesn't
occur.  But when you scroll up, the tooltip "Page 2 4/5 -B
Experimental Data Needed to Derive the DC Model Parameters" appears to
corrupt the screen display, and the residue of the corruption remains
after you stop scrolling.

Secondly, it appears that when scrolling up, there is a more subtle
corruption that occurs.  This corruption appears to originate at the
horizontal line at the bottom of the screen, the line where the text
in Writer emerges from.  Sometimes the corruption appears to be the
bottom pixels of a line of text, get stretched in the vertical
direction.  Other times, stray pixels or little line segments get
deposited between lines of text, in the whitespace.

This looks like it is being dealt with. I will add the "oooqa" 
keyword.

Is there anythig that can be done/improved in GSL?
I noticed that disorders caused by the tooltip can happen almost any
time,  it seems especially when XIO bandwith is low.
I played around with SAL_HIGHPRIORITY_REPAINT seemingly without any
changes. 
I guess this is different from a forgotten repaint in Writer.

cp->us: conceptional problem. we are using the screen as a double
buffer storage without having real control over its contents, not for
1.1.1.

cp->ssa: we need to fix this for 2.0, eventually together with
thorstens canvas or correct double buffering (or save under).

We have similar problems on windows, too. Scrolling under systen
windows is not perfect yet.
