Windows 10 (21H1) laptop, 1080p res display, with Intel Iris Plus GPU and Driver Version 27.20.100.9466 Version: 7.3.0.0.alpha0+ (x64) / LibreOffice Community Build ID: 05ff3d67d0e2e436406786c949eb7cfca107ba33 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 Unable to launch with Skia Vulkan rendering.

GPU/driver pair are not denylisted [1] Is there some way to force the LO launch with Skia Vulkan rendering force enabled? Or would the force only bypass a denylist entry (which isn't present here). =-ref-= https://opengrok.libreoffice.org/history/core/vcl/skia/skia_denylist_vulkan.xml
@Luboš, this was unexpected. Is there any thing I can provide that would help you tease out why the sudden change for this pretty generic Windows 10 Intel GPU & driver not launching with functional Vulkan rendering?
@Luboš, * --ran bibisect against bibisect-win64-7.3 but that was only updated through the 2021-08-19 builds of master. Regression somewhere in the range: https://cgit.freedesktop.org/libreoffice/core/log/?qt=range&q=5aac78e5fb241050a86714687e9ff8804588ae3c..05ff3d67d0e2e436406786c949eb7cfca107ba33 In that range do see a few Skia related commits including the work for Skia support in macOS; and you mention a fix for Vulkan crashing to be able to update beyond skia/m91 in https://gerrit.libreoffice.org/c/core/+/120967 but I didn't see specifics for how you fixed that.
Luboš Luňák committed a patch related to this issue. It has been pushed to "master": https://git.libreoffice.org/core/commit/2a0f2f074dd643b723bfbcc5c96e4f5ee8da87a3 fix Skia flushing to screen on Windows (tdf#144145) It will be available in 7.3.0. The patch should be included in the daily builds available at https://dev-builds.libreoffice.org/daily/ in the next 24-48 hours. More information about daily builds can be found at: https://wiki.documentfoundation.org/Testing_Daily_Builds Affected users are encouraged to test the fix and report feedback.
