Graphics card: GeForce GTX 1050 Ti/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 430.86

Blender Version
Broken: version: 2.80 (sub 74), branch: master, commit date: 2019-07-11 13:50, hash: 06312c6d2d
Worked: (optional)

Short description of error
[Please fill out a short description of the error here]
On sliding the 2 particular selected edge loops, both loops move unexpectedly while "Show Transparency/X-Ray" is disabled.

Exact steps for others to reproduce the error
[Please describe the exact steps needed to reproduce the issue]

Based on:
[the attached "bug_report 2019_07_12 IST_23_00.blend" file and the auto-fetched system info]

Procedure:
1* Open the attached file (tested only on the mentioned PC+software configuration)
bug_report 2019_07_12 IST_23_00.blend
2* With cursor in either of the view, press 'g' twice or search for "Edge Slide" and select "Transfer: Edge Slide".
3* Move the cursor, and see the edge loops moving.
4* To come out of the Edge slide tool, press "Escape".
5* Repeat from step 2 with cursor in other view.

Observation:
In step 2, If the cursor was in:

the left hand view (X-ray/transparency disabled), both the edge loops move differently.
the right hand view (transparency enabled), both the loops move together as expected.

For the records, if I change the view angle a bit this works.

I have never reported a bug before (for any project, ever), and I dont know if i should be or not, but I am a little bit excited that even after being such a newcomer to Blender and bug reporting in general, my report was understandable and not missing something. I was a little bit afraid to post it when I read the instructions saying to use latest "daily" build only.

Anyways, @dfelinto I would like to know, if possible, that what can cause a particular selection to behave differently? As far as I can guess, I think it is because the particular view angle and type is somehow being interpreted in a different context and then transformed accordingly. Can this be so, and is it so?

Not sure, but based on mano-wii's patch the occluded geometry is handled differently than the non-occluded. So there is that.
