After that failure, relaunch or next launch will be with Vulkan GPU acceleration disabled. The "Force Skia software rendering" still uses the Skia libs to control GPU but shifts to a raster frame based rendering. Unchecking both Skia related items, reverts to GDI based graphics rendering. That can be CPU only or Hardware accelerated. So there are actually four (4) rendering paths. The Safe Mode... dialog is a little unclear. When it launches it opens with GDI rendering, with Hardware Acceleration controlled by CPU. IIUC the 'Configure' section to 'Disable hardware acceleration (OpenGL, OpenCL, Vulkan)' will shift from Vulkan vector to raster frame based GPU--but is more directed to not use OpenCL for Calc formulas or OpenGL calls in Impress animations. And of course resetting to Factory settings and restarting sends you back through the GPU test loops. There is a QA/dev option to denylist specific GPU hardware and Vulkan driver combinations. That prevents the initial testing of the GPU with Skia Vulkan calls and launches directly into Skia lib raster frame mode. We would need the content of the skia.log from %APPDATA%\LibreOffice\4\cache when the Vulkan details are written. Something like this (from my nVidia GPU) RenderMethod: vulkan Vendor: 0x10de Device: 0x1380 API: 1.3.277 Driver: 552.48.0 DeviceType: discrete DeviceName: NVIDIA GeForce GTX 750 Ti Denylisted: no But can't use it if your skia.log says: RenderMethod: raster Compiler: Clang Which will happen when the Vulkan graphics tests fail, then on restart you fall back to skia raster rendering--or if you have forced raster rendering from the Tools -> Options -> View panel Please post what you have, or can figure out for your GPU and Vulkan driver. We have found the GLView utility [1] from realtech-vr.com to provide usable details. =-ref-= [1] https://www.realtech-vr.com/home/?page_id=1402 Referenced Bugs: https://bugs.documentfoundation.org/show_bug.cgi?id=129062 [Bug 129062] [META] Skia library bugs -- You are receiving this mail because: You are the assignee for the bug.
