LibreOffice was running OK on Windows, then a day or two ago it installed a new version (without asking me whether I wanted it). The new version doesn't run. An attempt to open either the application or a document results in nothing visible on screen. Task Manager shows two or three LibreOffice processes apparently running but doing nothing (0% CPU). The shortcut on the desktop says 25.8 but I have no idea whether this has been kept up to date by upgrades. I see an .msi which includes 26.4.2 dated 30/6 on my disk but have no idea to what extent, if any, it succeeded in installing itself.
Running it in safe mode (from the command line) and then "disable hardware acceleration" seems to make it work again.
Can you attach to this report the file: %APPDATA%\Roaming\LibreOffice\4\cache\skia.log We may need to put another graphics driver into the Skia denylist.
The entire content of that file is: RenderMethod: raster Compiler: Clang

Ok, this seems relevant: Intel UHD Graphics 630 ---------------------------------------------------- [Video Chipset] Video Chipset: Intel UHD Graphics 630 Video Chipset Codename: Comet Lake-S GT2 Video Memory: 1024 MBytes [Video Card] Video Card: Intel UHD Graphics 630 (Comet Lake-S GT2) [G1] [ASUS] Video Bus: PCIe v2.0 x0 (5.0 GT/s) @ [DISABLED] GPU Type: Integrated Video RAMDAC: Internal [Performance] Graphics Processor Clock: 345.0 MHz Graphics Memory Clock: 1314.0 MHz Resizable BAR (ReBAR) Support: Not Supported Hardware ID: PCI\VEN_8086&DEV_9BC8&SUBSYS_86941043&REV_03 PCI Location (Bus:Dev:Fnc): 0:02:0 [Driver Information] Driver Manufacturer: Intel Corporation Driver Description: Intel(R) UHD Graphics 630 Driver Provider: Intel Corporation Driver Version: 27.20.100.9078 Driver Date: 09-Dec-2020 DCH/UWD Driver: Capable DeviceInstanceId PCI\VEN_8086&DEV_9BC8&SUBSYS_86941043&REV_03\3&11583659&4&10 Location Paths PCIROOT(0)#PCI(0200) The denylist is here: https://git.libreoffice.org/core/+/refs/heads/master/vcl/skia/skia_denylist_vulkan.xml
Tim: if you would like to help, you could temporarily activate hardware accelerated Skia from Tools - Options - LibreOffice - View - uncheck Force Skia software rendering and then try to get a backtrace as advised here: https://wiki.documentfoundation.org/How_to_get_a_backtrace_with_WinDbg Under the "Debugging" section there is: "If LibreOffice crashes before it fully starts, then in WinDbg, press Ctrl + E or click File ▸ Open Executable.... In the dialog that appears, locate and select soffice.exe from the folder in which it is installed and check the Debug child processes also checkbox at the bottom of the dialog."
After typing "g" on the WinDbg command line nothing happened for several minutes. Then a top level window with title "LibreOffice" did actually open, with no content (completely blank and white). Some minutes later the GUI appears. There is no "crash". The problem is the many, many minutes it takes to open the GUI. So I can't follow the rest of the instructions to obtain a backtrace. In case it's of any interest the content of skia.log is now: RenderMethod: vulkan Vendor: 0x8086 Device: 0x9bc8 API: 1.2.159 Driver: 0.402.886 DeviceType: integrated DeviceName: Intel(R) UHD Graphics 630 Denylisted: no
tim, yesterday was uploaded on the website a new version, 26.2.5, please see if this is solving your issue.
(1) I installed 26.2.5.2 (2) In Tools / Options / LibreOffice / View I unchecked "Force Skia software rendering" (3) I restarted LibreOffice. It appears to run normally. I observe that "Use Skia for all rendering" is checked and greyed out - I'm guessing that this in consequence of my hardware now being blacklisted. So as far as I can see it's all OK now - thanks.
