'context mismatch in svga_sampler_view_destroy' Error.

[March Castle]

Hello,

One of my copies of Metashapes frequently freezes between workflow processing steps and I am forced to close the program.
When I do, the console prints the following: 'context mismatch in svga_sampler_view_destroy' - see attachment for screenshot.

I think this is related to the graphics card, but i'm not sure which steps to take to avoid this happening.
Has anyone else had this come up?

Thanks for your help, March.

Hello March,

Can you please provide a copy of the starting lines from the Console pane of the newly opened Metashape application?

Also please specify, if you are working on the machine remotely or working in the virtual environment?

Hello March,

Is there any GPU installed on the remote machine?

And whether running Metashape in ANGLE compatibility mode solves the problem:

Code: [Select]

metashape.exe --opengl angle

[March Castle]

Yes a GPU is installed.
How do I run Metashape in ANGLE compatibility mode using the code included in your previous reply?

[March Castle]

Found the article on your site about how to run in ANGLE mode. Now I get this error:

renderer_qgl.cpp line 615: glDrawArrays(encodePrimitiveType(type), (GLsizei) offset, (GLsizei) countElements(type, count)) failed: Out of memory

Hello March,

Which GPU is installed on the remote machine and what is the driver version?

[March Castle]

NVIDIA Tesla M60 with Driver ver. 26.21.14.4122 (released 07/11/2019)

[Alexey Pasumansky]

So do you observe OpenGL errors in the Console right after starting the application without loading any project or if they start to appear when you open some project and switch to mesh view mode, for example?

If there's a possibility I suggest to install the newer driver version, looks like there is driver released this March.
