Description Reinhard Lamsfuss 2016-08-04 21:55:44 UTC
User-Agent:       Mozilla/5.0 (X11; Linux x86_64; rv:45.0) Gecko/20100101 Firefox/45.0
Build Identifier: LibreOffice 5.2.0.4

Scrolling through a document which contains embedded ods tables or just writer tables lags behind mouse wheel movements and makes document editing impossible. Extremely sluggish. Show-stopper. 

Reproducible: Always

Steps to Reproduce:
1.  Open a writer document which contains embedded ods tables or just writer tables
2. Scroll through the document with mouse wheel
3. The scree display shows a significant retard resulting in a discrepancy between wheel movement and display. 
Actual Results:  
Create any writer document and embed some tables in it. Open with LO 5.2. Check scrolling behavior. It will show a significant lag. 

Expected Results:  
Smooth scrolling like in LO 5.1

Could you attach an example document? Perhaps my machine is too powerful as I could not reproduce..

Set to NEEDINFO.
Change back to UNCONFIRMED after you have provided the document.

No problem here.

Not reproduced with v5.2.0.4 / Ubuntu 16.04 or Windows 7 (UI render: default).
Is OpenGL turned on? If it is, it might be worth to try after turning it off (for details see the relevant part of [1]).

After turning on OpenGL in Windows 7, scrolling sometimes halts for a little bit, and I'm getting somewhat sluggish zooming.

I have OpenGL turned off by default, LO on my system doesn't even tolerate OpenGL. Might have to do with the graphics card. When I check the OpenGL box, LO will start with black boxes and unreadable menus. 
BUT: former versions up to 5.1.4 worked without this problem. 

System info: 
AMD Phenom(tm) II X2 550 Processor × 2 
GeForce 7025 / nForce 630a/integrated/SSE2
Debian GNU/Linux 8 (jessie) 64-Bit

I have found a workaround: Save the document in question created with former versions of LO (5.1.4, in my case) with LO 5.2.

The problem disappears and scrolling returns to normal once the document is saved ("save as" command) from within LO 5.2.

What remains odd is that the sluggish scrolling keeps appearing when opening with embedded tables created with former LO versions-

Which VCL plugin are you using? gtk2 or gtk3 ?
I both packages libreoffice-gtk2 and libreoffice-gtk3 are installed, you can switch between gtk plugins with the SAL_USE_VCLPLUGIN environment variable:
In a terminal, for gtk2, type
export SAL_USE_VCLPLUGIN="gtk"
libreoffice
or for gtk3 type:
export SAL_USE_VCLPLUGIN="gtk3"
libreoffice

I guess the bug appears only with gtk2 and not with gtk3. Could you try to confirm?

Best regards. JBF
Comment 9 Aron Budea 2016-10-02 12:23:42 UTC
Please test with the following additional combination as well:
export SAL_SYNCHRONIZE=1
(so once for each SAL_USE_VCLPLUGIN without this, then once with this)

For reference: bug 101189
