Short description of error
While trying to toggle between Material Preview and Rendered mode, the view will not update and only display as if Material Preview was selected. Clicking any other option or doing any action in the viewport (like holding the middle mouse to rotate the view) will trigger a refresh, however, multiple clicks between both modes will not trigger it. This behavior only happens on EEVEE, Cycles works as expected.

Exact steps for others to reproduce the error
On a new file, make sure EEVEE is selected as render engine; click on Material Preview, then click on Rendered, the viewport (if its replicable) should not refresh, and can be seen that toggling between those two options makes no difference, as the view will remain in Material Preview. Changing back to another mode, or interacting with the viewport will trigger a refresh.
This mainly happens when toggling from Material Preview to Rendered, Rendered to Material Preview updates as expected (The first time); however, if the viewport is already stuck on Material Preview, Rendered mode will not update when toggling back.
