System Information
Operating system: Windows 10 64-bit
Graphics card: ATI Radeon HD 5670

Blender Version
Broken: 2.82
Worked: at least 2.8

Short description of error
When I try to move a vertice it seems like the mirror modifier gets applied in an odd way. The result even changes when moving the camera or hide one of the images I use for reference. In fact it becomes distorted when hiding the images.
The following link is a recording of my screen:
https://drive.google.com/file/d/1nMcav4BC-5rgHh4AyBaelUOIKxwbE-p5/view?usp=sharing
I encountered this bug only recently. The file itself is older and I do not remember which version I used (since I use it via Steam I did not pay attention to the automatic patches).

Exact steps for others to reproduce the error

Open this file Bugged Project.blend
Disable visibility of Subdivision modifier for Edit Mode (which should already cause the bug)
Move a vertice

I can't redo this error in 2.82 release or master ca72ff599a.

Do 2.80, 2.81 work?
Can you double check if this happens after loading factory settings?

I opened the file in 2.80 without any sightings of this bug.
Loading factory settings in my current Steam version wouldn't change anything yesterday or today and I even installed it anew but the bug still exists. It looks like everything is normal on startup but as soon as I change visibility of the mirror and subdivision modifiers it goes back to what you can see in the video.

@publicStupidity please upload the file at the point where transforming fails.
It's possible something you're doing causes the issue to fail, which I'm not doing.

Also, check if this error exists in 2.81.

It's not really a transforming failure I realized. I just need to change some options for the modifiers and it does weird things to the selected vertices without me moving them, if I move them though it starts to get as messy as in that video.

File.blend

These screenshots are all made in 2.81 with the current state of the file. 2.8 loads it without these weird lines to the center of the object.

When loading it in my Steam version it starts out with the same weird lines but as I change the visibility options for the subdivision modifier they vanish. Here it seems to bug out at random though after going through different settings (multiple times for both mirror and subdivision).

I'm not sure though if the new file will make a difference for you since "Bugged Project" already looked like this for me on startup (screenshot also taken in 2.81). This file also looks normal on startup in 2.8 (meaning the line going to the right side with a vertice I never placed there is gone).

I should note this is what I see with the images disabled, once I make them visible the vertices get placed to a certain spot in relation to the image axis or something like that (as seen as in the screenshot of "Bugged Project"). You could see in the video what happens when I move the vertices along the Y axis: the whole object turns transparent and the regular gray object appears rotated in correlation to one of the images.
To me it seems like the mirror modifier is broken. At least with On Cage enabled for this modifier it looks broken.

Note that this report is still missing exact steps to redo the bug, which would be good to list so others can be sure they're checking the same issues.

However this may be spesific to your hardware, since we would be getting a lot of reports if it was common issue.
Both 2.82 release & master work here.

Upgrade your graphics card drivers (if they're outdated).
Try this file on another computer, to see if you can redo it elsewhere.
Try this outside of stem (official blender.org download)
Try 2.83 daily build.
Try to re-create this situation with a simple file (cube or suzzane), to see if there is something in this file which causes the problem.

Upgrade your graphics card drivers (if they're outdated).
The graphics card driver is up to date as the graphics card I stated in the first post is rather old. It would be unfortunate if that is the cause of this bug but at least I do not encounter this in 2.80...
Try this file on another computer, to see if you can redo it elsewhere.
It in fact worked fine on another computer with the current Steam version of 2.82.
Try this outside of Steam (official blender.org download)
That's what I already did as it's not possible to chose a version through Steam as far as I know (and I had checked the 2.82 version there as well)
Try 2.83 daily build.
It's a similar result there as well for my computer.
Try to re-create this situation with a simple file (cube or suzzane), to see if there is something in this file which causes the problem.
I tried it with a cube: This only happens with an image loaded into the scene, doesn't matter if it was inserted through Empty -> Image or Image -> Reference / Image -> Background. For some reason there is a cube around the image with the initial cube right inside of it. This cube vanishes once switched to edit mode though and won't affect normal editing of the vertices in any way. However as soon as I cut the cube in half and add mirror on it every vertice of the cube is attached to a vertice of the cube that got created by inserting the image. It's not visible when adding the mirror but as soon as I move any vertice of the actual cube the attached vertice of this "image cube" that shouldn't be there will move as well but not always into the same direction as apparently the axis of that object is rotated.

If this is in fact mainly a hardware issue then I'm sorry if this was just a waste of time but it's kinda odd to me that this suddenly happens after 2.8.

Thanks for the feedback, the transform code doesn't use the GPU, so it's strange that an image causes the vertex to be transformed differently.

Ultimately, unless a developer can redo this issue, we may have to close this task.

It would be good if someone on Windows with an ATI Radeon HD 5670 (or similar GPU modal) could test.
