Short description of error
I have a house with some trees around it that use a masked transparancy for the leaves.
When i bake the lighting for eevee (irradiance probes + several reflection cubes) the impact of these trees is massive. in 2.92 i had about 60fps, and in 2.93 its down to 10fps (when hiding the vegetation collection, it basicly runs like the 2.92 version with vegetation)
When i have a sunlight shining trough these masked leaves, it runs fine. but when the scene has baked eevee lighting, the performance goes down alot.
Exact steps for others to reproduce the error
Opening my attached scene 2.92, bake the indirect lighting as it is set up, and view the rendered viewport. Now repeat these steps in 2.93 (everything in this file is deleted exept the relevant items for this bug)
