Short description of error

While Gizmos are on ( like transform ) there is noticeable lag when rotating the view in a blender.

This can be noticed only when another background apps are not using hardware acceleration.
All need to be disabled to replicate, that includes chrome running WebGL or NVIDIA Experience.

*How to Replicate*

  • Run only blender app without anything in the background
  • enable transform gizmo
  • rotate the view

Event Timeline

Try this:

I had a similar problem but it was not related to gizmos. It's just that Blender has some issues which cause nVidia GPU's to constantly start idling.

Still noticeable slowdown,
I tried other options as well,

on the other hand
if I change the active tool to the cursor that is not using the gizmo
or with gizmo, if I open chrome and some site that uses WebGL, instant speed up, without closing blender

I also replicated that on Wacom companion 2, win10 intel card

Cant seem to be able to reproduce on linux (nvidia 970m).

@Clément Foucault (fclem), @Brecht Van Lommel (brecht): does that ring a bell somehow?
