Description Doug Ty 2019-05-25 07:16:21 UTC

I've recently updated to mesa 19.0.5 on Arch Linux, and it's consistently crashing Blender for me -- reverting to 19.0.4, everything is fine again.

Using the development build of Blender 2.8 (tested with 2019-05-24 caf52e3779a9), mesa 19.0.5 crashes upon selecting any geometry inside Blender. This renders Blender quite unusable, so unfortunately this is a pretty show stopping issue for me.

To reproduce:
1. Open Blender and select the default cube
2. Press tab to enter edit mode
3. Click on a vertex (and crash)

OS: Arch Linux x64
Kernel: Linux 5.1.4
Mesa: 19.0.5
LLVM: 8.0.0
CPU: Ryzen 2700X
GPU: Vega 56

Please let me know if further information is required. I am unsure of how to generate a meaningful log from Blender.

Update:

This also happens with the latest development build of mesa (19.2.0_devel.111215.1dc593e9b93 as compiled via mesa-git package on AUR)


I believe this is related to Bug 110721:
https://bugs.freedesktop.org/show_bug.cgi?id=110721

...As reverting "mesa: unreference current winsys buffers when unbinding winsys buffers" fixes the crashing in Blender (in addition to the issues presented in the other bug report.)

Using master + reverting that commit seems to resolve the issue for me.
