Fix T96524: Regression: The Material Preview doesn't show 

The preview does not work well with deferred render result pixels
allocation: it breaks the refresh and requires to toggle current
panels.

Since there is no tiled rendering for previews we don't save any
memory by deferring pixels allocations, so do it for the render
result during the render result creation.
