I'm not seeing the flicker on Linux + kde5.
On Windows, I can see it, if I move the mouse quite fast back and forth between
3 thumbnails.

--- Comment #26 from QA Administrators  ---
** Please read this message in its entirety before responding **

To make sure we're focusing on the bugs that affect our users today,
LibreOffice QA is asking bug reporters and confirmers to retest open, confirmed
bugs which have not been touched for over a year.

There have been thousands of bug fixes and commits since anyone checked on this
bug report. During that time, it's possible that the bug has been fixed, or the
details of the problem have changed. We'd really appreciate your help in
getting confirmation that the bug is still present.

If you have time, please do the following:

Test to see if the bug is still present on a currently supported version of
LibreOffice 
(5.2.5 or 5.3.0  https://www.libreoffice.org/download/

If the bug is present, please leave a comment that includes the version of
LibreOffice and 
your operating system, and any changes you see in the bug behavior

If the bug is NOT present, please set the bug's Status field to
RESOLVED-WORKSFORME and leave 
a short comment that includes your version of LibreOffice and Operating System

Please DO NOT

Update the version field
Reply via email (please reply directly on the bug tracker)
Set the bug's Status field to RESOLVED - FIXED (this status has a particular
meaning that is not 
appropriate in this case)


If you want to do more to help you can test to see if your issue is a
REGRESSION. To do so:
1. Download and install oldest version of LibreOffice (usually 3.3 unless your
bug pertains to a feature added after 3.3)

http://downloadarchive.documentfoundation.org/libreoffice/old/

2. Test your bug
3. Leave a comment with your results.
4a. If the bug was present with 3.3 - set version to "inherited from OOo";
4b. If the bug was not present in 3.3 - add "regression" to keyword


Feel free to come ask questions or to say hello in our QA chat:
http://webchat.freenode.net/?channels=libreoffice-qa

Thank you for helping us make LibreOffice even better for everyone!

Warm Regards,
QA Team

@Kendy,

With OpenGL issues resolved (reworked buffering and effective black listing),
would there be a lot of work in providing less graphically demanding mouse over
behavior on the Start Center and Template Manager backingwindow, and for
tooltip movement, for when hardware acceleration is not active or is blocked?

If not, suggest we close residual as WONTFIX.

--- Comment #23 from V Stuart Foote  ---
And as in comment 18, and initial description, this is now exclusively an issue
of redrawing the thumbnail view or icon when mouse over focus shifts or as the
tool tip is being repositioned.

It is normal, consistent and is acceptable given that that portion of the
canvas is being redrawn.  It is less noticiple in OpenGL because it is
accelerated, and it is not overly objectionable as it is rather hard to
reproduce--slowly pushing the tool-tip to force the redraw of that thumbnail is
hardly a normal action.

I'd say it is good enough and be done with it -- believe we can close WONTFIX. 
Alternative of "anchoring" the tool-tip is much less appealing.

... but in the case of toolbar icons, I see the flicker only when not using
OpenGL. So maybe not the same root cause after all.

--- Comment #20 from Tor Lillqvist  ---
This flicker might be a generic problem with thingies that are displaying a
tooltip. If you slowly move the mouse cursor between tool icons in the toolbar
of Writer, for instance, so that the tooltip stays visible (and its contents
switches as you move the cursor between icons), you will notice, now and then,
that the icon you are leaving and/or entering flickers. Probably it is much
more noticeable for the start centre thumbnails just because they are much
larger and take a little longer to draw.

The ghosting / off-by-one error is fixed as bug#96858. Tor is tackling OpenGL
related flicker under Windows in a similar way as for gtk+ too. Glad it's
working nicely under Linux for you (though to use GL under Linux you need
SAL_USE_VCLPLUGIN=gtk - gtk3 erroneously claims it is working, when it is not
;-)

On Windows 8.1 Pro with
Version: 5.2.0.0.alpha0+
Build ID: 4a8c0d313540bd78c9c381edd548b976c580ca9a

Locale: en-US (en_US)

The off by one of the tooltip has been eliminated! Thumbnail views on
backingwindow are clean. 

Any "Flicker" is gone--except for the still noticible redraw of the onmouseover
background for the active thumbnail.

As mouse cursor is repositioned, the tooltip is redrawn in a new location. That
triggers a clear and apply of the onmouseover background.  Might look like a
"flicker", but it clearly follows the redraw of the moving tooltip.

On Fedora 23 w/LXDE (as guest on VMWare Workstation 12 on Windows 8.1) and
Version: 5.2.0.0.alpha0+
Build ID: 8a342e9f6ad701bd46ecca1c3d270ef2d9670d44

The flicker while redrawing each thumbnail is, at this point following
Michael's patch, not as noticeable as under windows. However the tooltip
filename ghost behaves the same. 

Present until the StartCenter is resized or redrawn by component launch. When
OpenGL is disabled the "ghosting" of the tooltip frame vanishes.

As in movie clip comment 10.

Unfortunately for this build, no opengl_device.log being written to
settings/cache directory.

Michael, *

On Windows 10 Pro 64-bit with

Version: 5.2.0.0.alpha0+
Build ID: 917d59a84124d1022bd1912874e7a53c674784f1

Locale: en-US (en_US)

The tool-tips display of file name is still leaving a trail of redraw edges as
it is pushed by mouse down the backing pane of the thumbnail view of Start
Center.  

Also, don't see too much reduction in the "flicker" as each thumbnail is
redrawn as the tool-tip repositions.

It only occurs when OpenGL is active, but may be a different facet than the
double buffering you've been working on?

Hah - so my patch removes GL related flicker; but for this case, it's
un-related to GL AFAICS and was here from 4.2.0 ... so ;-)

The re-paint dirt is another bug that got tangled into here; but the flickering
is prolly easy enough to fix - will have a look =)

Thanks !

With OpenGL active tooltips or file path "tip" are "off by one" when cleared as
the tip is moved with mouse pointer movement. Leaving trails across the
StartCenter until the screen is refreshed or resized.  The flickering on redraw
is momentary--but the trails are persist.

When OpenGL rendering is disabled--the tooltips or file path "tip" is correctly
disposed as the next is drawn. The "flicker" also is gone.

When Tools -> Options -> View: "Use OpenGL for all rendering" is turned off,
the tool-tip does not leave a trail.

@Kendy,

Can the drawing of the tooltip on mouse movement be adjusted to not also
refresh the active thumbnail?

Have another aspect to the canvas redraw while the mouse cursor moves and the
tool tip pop-up follows it.

As cursor is moved, and tooltips with file name and path are redrawn to follow
along, the old border from the tooltip is not being erased.

Results in a ~1px white line for each tooltip as it relocates that was the old
top edge and right edge of the tooltip. That ~1px line remains until the whole
canvas is redrawn with a scroll bar movement or selection of a document or
activation of a module.

I'm sorry but I think there is a mistake. From my point of view there is no
relationship between this bug and bug 71807 [Drawings (in Writer) embedded in
document corrupted on saving. Rest of document is fine.]. May be another bug is
meant. Hence set Status back to NEW.

No, confirming and setting this back to new.

The issue is a canvas refresh, but it looks to come from movement of the
Tooltip containing full file path. As cursor is moved, the Tooltip repositions
and causes the entire thumbnail view canvas to be redrawn.

If you check on Tools -> Options ->  General: Extended Tooltips, which without
local help installed shows a generic tooltip for the thumbnail views that does
not reposition as the mouse moves.  There is no "flash" as the mouse traverses
the frame.

This is different on my system (German UI, German local help installed(!),
extended tool tips checked): The german generic tool tip is displayed. If you
'touch' this tool tip with the mouse pointer the position of the tool tip
changes and the canvas also flickers in this case.

Furthermore with extended tool tips checked and local help installed, the
flickering also occurs if you display the templates within the start center and
'touch' the displayed tool tip.

Yes I see that also, but I have to work to get the generic tooltip to appear at
a location over a thumbnail.

Point was, that if the local help is not installed, by checking extended tips
it is more obvious the issue is screen flash related to the canvas redraw of
repositioned tooltips moving in response to the mouse movements.  The generic
tip that shows with extended tips selected is for the whole StartCenter and
does not get bumped around--as much--by mouse cursor movements.

Yes, there is a noticeable flash during redraw. Believe it is an ongoing
buffering issue, more noticeable at 5.0 release with change in StartCenter
color scheme. None the less this is clearly a duplicate/continuation of bug
71807
