System Information
Operating system: Windows-7-6.1.7601-SP1 64 Bits
Graphics card: Intel(R) HD Graphics 530 Intel 4.4.0 - Build 21.20.16.4839

Blender Version
Broken: version: 2.80 (sub 59), branch: blender2.7, commit date: 2019-04-24 22:25, hash: d966c2f0c2
Worked: (optional)

Short description of error
When I try to edit UV with faces display turned off, all mesh disappears. Then, then I click faces display on, whole application closes.

Exact steps for others to reproduce the error

Launch Blender with default scene.
Activate "UV Editing" workspace. Make sure you are in edit mode on the right pane and at least one face is selected.
On the left pane click "Display" and turn off "Faces".
On the left pane select at least one vertex and try to move it with "G" key.
Whole unwrapped mesh disappears (this alone is buggy - expected behavior is: selected vertices are being grabbed, whole mesh is still visible).
On the left pane click "Display" and turn on "Faces".
Blender closes immediately.
