Crash does not depend on the floating Sidebar deck active, just dragging wider and passing the edge of the main LO window frame results in crash.  Does not occur with Skia Raster rendering mode--just Vulkan for this GPU/Driver pair.

Luboš: since it concerns Skia, thought you might be interested in this one.

STR (undocked sidebar and minimumwidth set false, dragging width across main frame edge) do not crash.  Will see if driver update for the Quadro K2000 has any effect.

WinDbg stack trace of crash with nVidia GPU and Skia Vulkan rendering

updated driver to nVidia 471.11 (2021-06-21)

Still getting crash with STR and with Vulkan rendering with this GPU

Attached soffice.bin to WinDbg session and get this stack trace with LO build symbols, if it helps.

Also got slightly different signature, with this crashreport

Hello V Stuart,
is this issue still reproducible in a master build ?

Yes still happens. Refinement for the STR:

1. open Writer
2. Undock Sidebar, should be floating middle of document canvas
3. Grab SideBar's left edge (i.e. changes to horizontal resize mouse cursor)
4. drag it to left passing the LO application frame left edge
5. crash with Skia/Vulkan rendering, no crash with Skia/raster mode

All cases following the crash crossing the left edge of the app frame with Vulkan, the LO build will open having fallen back to Skia/raster mode.

So issue is something in the way the app frame is referenced for this nVidia Vulkan driver instance for this GPU.  Don't think we'd want to blacklist Vulkan generically for this nVidia driver.

OK, had an opportunity to test on a more modern nVidia Quadro RTX 4000

resize dragging width of the undocked SideBar deck across the app frame does not crash. A Geforce GTX-750 TI and this Quadro RTX 4000 have no issues with crossing the app frame.  

So, probably the best thing is to deny list the Quadro K2000 (Device: 0xffe) from Vulkan rendering.

GPU device IDs for nVidia product family GK107 -- 0x0fc0-0x0fff

Luboš, *

Doing some manual edits of the share/skia/skia_denylist_vulkan.xml, and got to looking at its syntax from driverblocklist.cxx/.hxx

Seems we can now only handle individual deviceIDs with some testing of vendor and range of driver versions. 

But, would there be any utility to handling devices from a block of vendor device ids? For example, the troubled nVidia K2000 here comes from the nVidia Product GK107, device IDs in range 0x0fc0-0x0fff

I'd not be surprised if all of the GPUs in the product block have the same flawed Vulkan (or OpenGL) rendering and the range could be treated the same.

Would it be worth some effort to be able to deny list and force Skia raster rendering by vendor block of device IDs in addition to our current driver only testing?

Apparently the way to block several devices is to list them like this: https://cgit.freedesktop.org/libreoffice/core/tree/vcl/source/opengl/opengl_denylist_windows.xml#n33 . Is that enough here? It'll be a number of lines, but it's not that many.

Revisting this while testing work on bug 125931

The floating SB deck being dragged across the vertical edge of the LO app frame will crash LO with Skia Vulkan rendering, no issue with Skia Raster rendering. More recent Vulkan driver does not help for this Driver/GPU pair.
