[libreoffice-users] LO Scolling problems under Windows.

[Dave]

I am encountering an increasing number of scroll rendering issues, with
ODF documents (.odt) opened in LO 5.3.4 and 5.4.0.2 under Windows 7, 8.1
& 10 The issue is that some (not all) documents take several seconds to
scroll single lines and up to a minute to scroll a few pages.

The issue does not manifest itself in LO 5.3.4 under Linux, AOO 4.3.1 or
LO 3.3 under Windows.

Is anyone else experiencing a similar issue, or is there a known
rendering problem in recent versions of LO?

LibreOffice has switched (don't know exactly which version) to OpenGL
rendering which is on by default in recent versions.

Go to Tools > Options and select on the left listing LibreOffice, View and
then uncheck "Use OpenGL for all rendering"

If this doesn't help, can you report a bug and append to it one of the
documents that causes problems?

Hi Pedro,

Yes, I was aware of this change and I always disable OpenGL rendering.

The issue is the same if the option is checked or not.

For a little added clarification, the documents in question contain very
few graphics (in most cases none) and the scroll delay issue occurs in
parts of the document containing nothing other than straight forward
formatted text (eg. no images, no frames, no columns, no page breaks, no
TOC, or other content where similar issues have been previously reported
in Bugzilla.)

hello.
i have version 5.3.4.1 and for me libreoffice is faster than previous
versions before 5.3!

Subjectively, 5.3.x & 5.4.x do seem to be slightly more responsive, more
so under Linux.

openGl is activated for users since version 4.4 of libreoffice and
switched to version 2.1 since version 5.1 of libreoffice which support
more modern systems and newer graphical cards.

Yes, I am well aware of those changes, but as mentioned previously
OpenGL does not appear to be the culprit in this instance.

hope that help and God bless you.

No, but thank you.

Regards
Dave

Thanks David,

Calc is not the module I am experiencing this issue with. Only Writer
and only some (.odt) files opened in recent versions of LO under Windows.
I can't exactly pinpoint in which version of LO this became an issue for
me, but I don't recall seeing this slow/jerky scrolling in 5.1.x
releases. I grab a couple of earlier releases and try to track this down
to a more specific version.

Dave
