Libre Office 7.0.0.3: Impress flickering transitions XFCE

Support Software & Applications

1

Hello forum,

I have asked on the LibreOffice forum and looked for solutions online about Libre Office Impress transitions flickering between black and the slide, even with a basic fade. The responder on the LO forum suggested checking VSYNC, but I don’t know where that is. Other solutions relate to disabling OpenGL, but that is not an option in the LO preferences.

GPU details:
Graphics: Device-1: NVIDIA GP107 [GeForce GTX 1050 Ti] driver: nvidia v: 440.100 Display: x11 server: X.Org 1.20.8 driver: nvidia resolution: 1920x1080~60Hz OpenGL: renderer: GeForce GTX 1050 Ti/PCIe/SSE2 v: 4.6.0 NVIDIA 440.100

This is the nvidia.conf file contents:

There should be an OpenGL option if you use the:

nvidia-settings

command in terminal.

There may be an option for VSYNC as well.

Thanks for that. I deselected each item one at a time and restarted Libre Office. No change in display.
