Description Karl 2013-12-25 01:11:50 UTC
scrolling a table with the sliders at right for up/down or bottom for left/right
creates artifacts, especially on FAST MOVEMENT

which resolves (!)/ disapear, if the mouse button (after slider movements) is released

I am not sure, if it relates to "viewing".

Win 7 / x64
Graphics-driver AMD Radeon legacy (HD 2400)

kind regards to all LO developers and all others

part of screenshot

I just took part of a sreen, without table contend.

The artifacts are created by duplikated column / row numbers.

In real cells and their contend ar "dubbled / manyfolted" the same way.

Thanks for the screenshot Karl. Guess we'll have to wait for some windows users to confirm this glitch. I cannot reproduce this on OSX.

creenshot 2 / duplicated cells

sorry, the lower part might be too small

upper is the cells in normal view,
below if thei are crolled by slider fast.

the cells are "duplicated" too.

originally the rightest cell is column "P"
then "duplicated up to coulumn "Y"


PS: the duplication "solves" if mouse button on slider is released

Hi Karl,

I don't reproduce using LO & Windows 7 Home Premium.
Can you verify In Tools > Options > LibreOffice > View in Graphics Output
that Use hardware acceleration is checked?

Thank you,

I have a similar problem but so far no one can reproduce it.
Look at the bug 72401: https://bugs.freedesktop.org/show_bug.cgi?id=72401
Comment 7 Karl 2013-12-31 07:13:57 UTC
Hardware Accell IS CHECKED,
but unchecking it doesnt change anything.

The lifetime of the artifacts is "until mouse button is released"

I can reproduce this bug running on Windows 7 
I can't reproduce this bug on mac 

here is a video to show that happens: http://youtu.be/vf00Nxuq41s 
(sorry for the bad quality)
Comment 9 Karl 2014-01-17 20:37:57 UTC
The same on LO (RC2)

kind regards
Comment 10 Karl 2014-01-26 01:32:53 UTC

I installed LO today 
and "srolled fast" through my tables.

I might say: I can't see the effects anymore.

Set to resolved works for me as the used said but found a dubplicate in the RC3 release note. so setting it as a duplicate
