Studiolight doesn't update in viewport
Closed, ResolvedPublic

Description

System Information
Operating system: Windows 10 Pro 64Bit
Graphics card: GeForce GTX 1080 8GB

Blender Version
Broken: (all 2.92 beta versions, as far as I can tell)
Worked: (2.91.2)

Short description of error
Rotating or changing the studiolight in the viewport shading options rollout doesn't update lighting in the viewport until either clicking in the viewport or rotating/panning/zooming in/out.

Exact steps for others to reproduce the error
Based on the default startup .blend file.
Switch the viewport shading mode to Material Preview.
Open the viewport shading options rollout and drag any of the sliders controlling the studiolight. The lighting and background of the viewport don't change until interacting with the viewport somehow, either by clicking inside the viewport or by changing the view (rotating, panning, zooming). Switching to a different studio light also doesn't update until interacting with the viewport.

Working fine now :)

The irony is that, after constantly downloading every couple of days and checking if this was fixed, the last version I checked this on was the nightly from january 26, literally a day before the fix :))

Thanks a lot and sorry for not checking the latest.
