Regression

Yes

Crash or freeze with artifacting on layout resize when changing the layout affecting Scene View and Game View simultaneously

Windows

-

Steps to reproduce:
1. Open the project attached by the user
2. Grab the border between Scene View and Game View and drag it left to right
(repeat step 2 for some time if it doesn't reproduce right away, dragging the Editor to other screens or having the Editor halfway from one screen to another and then trying to reproduce the issue seems to sometimes help reproduce the issue faster)

Reproducible with: 2019.3.0a10, 2019.3.3f1, 2020.1.0a24
Not reproducible with: 2018.4.17f1, 2019.2.21f1, 2019.3.0a9
Unable to test 2017.4 as the project breaks in that version

First lines of stacktraces the issue might reproduce with (crashes rarely):
0x00007FFE9D5E6DA0 (d3d11) CreateDirect3D11SurfaceFromDXGISurface
0x00007FF6743A5DB2 (Unity) StreamOutSkinPoseBuffer::Update
0x00007FF67438D6C0 (Unity) GfxDeviceD3D11Base::UpdateSkinPoseBuffer

0x00007FF673279BCE (Unity) memcpy_repmovs
0x00007FF670171756 (Unity) GfxDevice::UpdateBufferRanges
0x00007FF670AFED80 (Unity) GfxDeviceWorker::RunCommand
0x00007FF670B02D0C (Unity) GfxDeviceWorker::RunExt

When there's no crash, Editor quits with spamming this line in the Editor log:
d3d11: EndWrite on null buffer

Notes:
- Reproduces on both screens in a multi display setup
- In 2020.1 stream pops up TDR error window and quits
- Doesn't reproduce in Play mode
- Setting Layout to Default right after the project is opened renders the issue unreproducible

  1. Resolution Note (2020.1.9f1):

    Updating GPU drivers seem to render the issue not reproducible

    same happens to me i go to resize the game view to see if it scales correctly and if i do it a teeny bit to fast the whole editor freezes leaving the only thing i can do is to force quit
