This should be significantly improved in 5.0.2 RC2 (due this week). Please can
you re-test, and re-open if problems persist.

Thanks !

5.0.4 disables GL by default ;-) so - glad that fixes things for you - but
we'll leave this bug open in order to track the underlying problem.

Then again 5.1 is significantly improved performance-wise too =) thanks !

Today I installed LibreOffice_5.0.4_Win_x86 and all of the performance issues
seems to be history.

OpenCL is enabled with default settings.

System:
OS: Windows 8.1 Pro (64bit)
GPU: Nvidia GTX 770 (driver: NVIDIA 358.50)
CPU: i7-4770K
RAM: 16GB

Enabling OpenGL does lower the smoothness when scrolling and everything seems a
bit more sluggish (in 5.0.4).

I seem to have mixed the terms OpenCL and OpenGL, my apologies.

Tools - Options - LibO - View - Use OpenGL for all rendering

I am not sure what you mean by "5.0.4 disables GL by default". If I go to
Options -> LibreOffice -> OpenCL the "Allow use of OpenCL" is checked. Is this
setting ignored in 5.0.4?

I believe that I was using 358.50 when i tested 5.0.2, but if it was the
latest, at the time of testing, I don't know.

I experienced very similar behavior on 5.0.2. Disabling OpenGL did not solve
the problem (nor did resetting user profile). However, downgrading to version
5.0.1 did (even with OpenGL enabled).

After disabling the OpenGL rendering setting, the application became more

I'm assuming this is related, but I'm getting severe slowdown using drop down
menus, coinciding with massive jump in CPU usage. The product did not do this
in the previous release. Included is a link to an unlisted video to show the
exact behavior.

You restarted LibreOffice after changing the setting?
If yes, then your problem is not the same.

I should mention that as shown in the video, changing the OpenGL setting does
not show any effect.

Same problem as OP here. Also a Nvidia card (750gtx), windows 7-64. LO 5.0.2.2
Switching off OpenGL helps too.

We just found a rather silly thing here around shader re-compilation that
impacts performance; but - prolly not -that- much; will try to get that into
5.0.3 RC2.
