Open Classroom.blend
Change the 3d viewport view to Solid or Lookdev settings.
Make sure the Overlay - Navigate Gizmo is visible.
Move the mouse over the 3 icons. The 3d viewport shimmers.
This happens when moving the mouse over other parts of the interface.

I can confirm that the viewport seems to redraw

Yes this is because of the TAA and how the gizmos are drawn.

Fixing this would require increasing the Vram usage to have an isolated buffer only for gizmos.

Another way would be to have a dedicated redraw tag to avoid redrawing the shaded mesh (like cycles does).

Just to make clear, this isn't just gizmo related, just an example.

Outliner Editor seems to cause no issue
Properties Editor, for the most part no affect, although it happens intermittantly when moving the mouse up and down over left side icons (Render, Output, View Layer etc.)
Timeline Editor, no issue
Top Menu Bar, no issue
Bar with Transform, Annotations, View, 3D Cursor, Properties. When collapsed, no issue. When expanded, issue

Yes anything that tags the viewport for redraw will reset the TAA if it has already converged. This is because the TAA also uses the redraw tagging for refreshing.

previously - in old bge there was a concept of scenes and overlay scenes, background scenes

I think these were indeed separate buffers

This allowed us to render a scene offscreen and slap it over the top of another scene in real-time

Maybe this type of system could be restored but implemented in the compositor node code

ticking 'dont draw ui' simply skips rendering that buffer all together?

I also noticed it happens when rotating or panning, and without any gizmo or overlay. Kind of a workaround, but when I use the theme Oddysey (On the call for content thread) is not as evident, I changed to the default theme and that's were I noticed this bug.
