System Information
Operating system: Linux 4.9.0-8-amd64 (Debian 9 stretch) x86_64bit
Graphics card: GeForce GTX 1050 (2Gb)

Blender Version
version: 2.80 (sub 43), branch: master, commit date: 2019-02-05 15:52, hash: 08ab09cf04, type: Release
build date: 2019-02-05, 15:56:09

Short description of error
unwrapping default cube for texture-painting.
Opposite sides of cube end up adjacent in uvMap.
(ie; I have no control over where seams end up)

Exact steps for others to reproduce the error
Start with default scene with the original cube.
Cube:
tab [Edit Mode]
[Edge Mode]
A select All
menu: UV » clear_seam
alt-A select None
LMB select edges so that the -Y face (numpad-1) will be center of cross.
[Face Mode]
A select All
menu UV » unwrap (now staring at 6 faces in UV_Editor, unfolded like a cross)

Image_Editor:
create image and pack_as_PNG into file.
paint something on image.

Node_Editor:
setup nodes so that texture_coordinates and image_texture will map 2d painting onto 3d Cube (see .blend file)

3D_Viewport:
[Texture_Paint Mode] for immediate feedback while painting.

Please cancel bug-report with my apologies.
I did all steps from scratch twice before reporting bug.

Then I tried it by deleting the original cube and adding a new one. UV-unwrapping worked correctly.
Then I repeated it with the original cube, and UV-unwrapping worked correctly this time.

(starting blender 2.80 from scratch each time)

The apparent problem must be at my end. Sorry.
