Dependency graph problem with animations and textures in UV Editor?
Closed, ResolvedPublic


System Information

Short description of error
While playing an animation and viewing a texture image simultanously in the UV editor, the whole application break down to a very low framerate around 3-9 frames/s.
Closing the UV editor or removing the texture from view increases the application back to the origin speed. See the screen recording GIF file at the end of this post for details.

I've attached an example blend file to reproduce the problem.

Exact steps for others to reproduce the error

  1. Load the example file.
  2. Play the animation.

-> All is fine and the animation plays fast.

  1. In the right hand UV editor window there is no texture. Switch now to any texture by using the pulldown menu in the UV editor. (There are textures included in the example file.)
  2. -> The animation should break down to a few frames/second. If not, just zoom in or out the texture inside the UV editor. The animation speed should reduce at the latest now.

As soon as you close the UV editor window or close the texture, blender became fast again.

In the example situation the whole application (Blender) becomes slow and runs with some frames per second only.

Is this a dependency graph problem?

I can't reproduce this on my end. Does this still happen with the latest blender beta?

Tried it today with version blender-2.80-11c9702dd40f-win64
Problem still exists.

I've asked a friend to reproduce the problem with the todays version of b28. It's the same behavior. My friend has a different PC and use GeForce GTX 1070.

I guess you've forgot to zooom in and out the image in the uv editor window. See my reproducing steps.
Please zoom the image in and out several times, until Blender breaks down to a very low framerate.

Thank you

Bug fix confirmed in version blender-2.80-d30f72dfd8ac-win64.

Thank you, guys,
