Blender Version
Broken: version: 2.80 (sub 75), branch: master, commit date: 2019-07-29 14:47, hash: rBf6cb5f54494e
Worked: (optional)

Short description of error
In eeve rendering mode, in a brand new blend file in brand new blender install, when any sized plane is put into the 3D viewport, with the base cube, light source and camera, there by default in a new blend file, when put into eeve rendering, there is an unexplainable shadow strecthing across the plane from the only light source in scene.( the plane is in X and Y axis ),
The unexplainable shadow moves as the light source moves, more exact shadows are created with more light sources.

Exact steps for others to reproduce the error
Start up new blend file, and turn eeve mode, add a plane and strech it across X and Y axis exacly, then moving cube right above it to ''setlle '' the cube on the plane.

[Based on the default startup or an attached .blend file (as simple as possible)]

That's how it looks on my end. How does it look in your case?

@Dariusz (Dellishia) Please, more clarify prob...
Also provide screen-shot, How it looks like, as asked...

Sorry, i forgot to bring a screen shot along as to how it looked like, Tooday, as i turned on works fine, with no weird shadow from the light source ?....i am deeply sorry for this, i dont know why that occured, and how it '' fixed '' itself,? ( as it occured every time i turned on eeve )

I am deeply sorry to bother you,, if this will happen again for whatever reason, ill make sure to bring in a screenshot of it occuring, Its really weird how now it works fine, ill go back to you if it happens again ( or make a new thread with the screenshot if thats possible, thank you )

The bug occured again just now as you can see, there is an unexplained shadow from the light source in Eevee, doesnt occur in cycles. ( new blend file, i even loaded factory settings after it occured to see if it would happen again, and it did ), i dont know why it is happening, and why i fixed itself eariler, again ( all of the settings are on the default, as you start up blender for the first time )

i really dont know what , or why its happening D:

Edit : you can also see this shadow in the ''light preview'' :

@Dariusz (Dellishia) if you update your nvidia drivers to the newest version, does it still happen?
Can't reproduce this on the 5 computers I have access to. I think it must be something with that specific GPU.

Also please try in the newest Blender - you can download it here:
Just run the blender.exe after unzip

I have downloaded the latest driver's for my card, as well as the 2.8.1 Alpha build of blender, the problem does not seem to appear any longer as of right now, hopefully it wont happen again, if it does, i will make sure to let you know. Thank you for your patience !
