Description ggtylerr_contact 2021-07-23 09:34:01 UTC
Sorry if this is a pretty bad bug report, I just happened to see this happen randomly while updating and figured I should make a report.

Problem was only fixed after disabling hardware acceleration in Safe Mode. I'm pretty sure I didn't touch any settings regarding that, but just for safe measure, I'm assuming OpenGL was enabled.

Steps to Reproduce:
1. Launch software with hardware acceleration (and presumably same hardware and drivers)
2. See results

Actual Results:
Corruption occurs:

Expected Results:
UI should *not* look like this. As far as I know, the only thing that's affected is UI, but it's too corrupted for me to navigate.

Reproducible: Didn't try

User Profile Reset: Yes

OpenGL enabled: Yes

Additional Info:
Version: (x64) / LibreOffice Community
Build ID: 85f04e9f809797b8199d13c421bd8a2b025d52b5
CPU threads: 8; OS: Windows 10.0 Build 19043; UI render: Skia/Raster; VCL: win
Locale: en-US (en_US); UI: en-US
Calc: threaded

Hardware info:
CPU - AMD FX-8350
GPU - GTX 970

Driver info:
NVIDIA driver version 465.89
I don't know what other drivers are used, sorry.

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.
