Hi everyone, I’m having a bug which was not present about a week ago.
Every time I click the blender Icon in the Windows 10 taskbar to minimise it, it just completely shuts down. If I open a window within the blender UI, like the preferences window, and then close it, the whole program closes too. I have tried the following:
A fresh install of blender 2.79, 2.78, and the daily build of 2.80.
Setting blender back to factory settings.
Turning my PC off and on again
Updating NVIDIA graphics drivers.
Running Blender in compatibility mode.
Running the exe file direct from it’s location.
Running blender from the command prompt.
Running blender as admin (which my profile already is)
None of these worked.
I have not noticed this problem with any software other than blender and it is a huge, huge problem that makes it nearly unusable. Does anyone know what I can do?
What video card(s) do you have in the machine? Does it also have Intel integrated video support and are you sure Blender is running on the Nvidia and not the intel graphics? Not that this should be related for any particular reason to the problem you’re describing.
When you run blender from the command prompt, are any messages displayed when it quits, or does it just fall back to the command prompt?
If you’re seeing the issue also with 2.79b and 2.78 then definitely some sort of weird system issue then I guess and likely caused by something other than Blender itself, so what else has changed on the system since the last time it was working?
On the 2.80 command line run you can add --debug to see if that displays any more information at the time it exits (probably won’t).
Do you have a Wacom tablet type device and have you changed the Wacom software (or has it updated itself) recently? One user potentially solved a similar issue by removing the Wacom wintab32.dll. It had been affecting both the Steam 2.79 and 2.80:
I had the same problem, Win10, NVidia card, only Blender affected, didn’t matter which version of Blender, the slowdown started a few weeks ago after both a power outage and a Win10 update. It’s been weeks trying to find it, including all of the above plus rebuilding my OS. What finally worked was to pay more attention to how I was updating the NVidia driver - directly installing it was maybe a bad idea. I ended up downloading several from the NVidia website, then, in Device Manager, pointing at the folder where I stashed the drivers, and (I think) letting Win10 pick the right one, which is 11-1-2018, 25.21.14.1678 for a NVidia Quadro M2000.
