Bug#935810: blender: Crash to desktop on "toggle Rendered Shading" using "Cycles Render"
Package: blender
Version: 2.79.b+dfsg0-7
Severity: important
Dear Maintainer,
Hitting "Shift Z" which defaults to "Toggle Rendered Shading" makes
Blender crash to desktop.
This problem appeared after I switched from "nouveau" drivers (using
only the "discrete card" in bios settings) to nvidia propriatary
drivers + bumblebee + optirun and the bios setup for hybrid graphics
(Intel HD530 + Nvidia M1000M).
This only happens when runing Blender via "optirun" + rendering with
CUDA in "Cycles Render".
On crash, blender leaves the attached error text file in /tmp.
Best regards,
