<pre>OpenGL is gone, rendering is either by CPU or using Skia libs.
Skia has two modes--Vulkan (the OpenGL 3D vector rendering replacement), or
Raster
CPU rendering has two modes--GDI or CPU controlled Hardware Acceleration.
I would suspect your issue is with Skia Vulkan rendering, the nVidia GPUs have
had issues.
Please use the Tools -> Options -> View panel to set 'Use Skia for all
rendering' with the 'Force Skia software rendering' unchecked. The will enable
Vulkan rendering--and if the UI is garbled it should force a restart and the
'Force Skia software rendering' will be set on next launch.
You can tell if Skia 'Vulkan' or 'Raster' mode is active from the Help -> About
dialog. If Skia is disabled, the About will show 'default' for UI Render:
Since Vulkan support for your nVida GTX 970 based GPU is probably the issue
(and needs to be deny-listed) please provide the Vulkan driver details. Either
from the skia.log in %APPDATA\LibreOffice\4\cache or with a 3rd party app [1].
And, please confirm if the UI is well composed working in Skia Raster mode.
