Date: 2018-12-20 23:46
Branch: blender2.8

64-bit Linux build

Short description of error

This is a bug affecting vertex selection in edit mode when using some view other than wireframe view. It causes wrong vertices to be selected.

Exact steps for others to reproduce the error

Start Blender with the default startup file.
Zoom in to the default cube
Apply Subdivision (Catmull-Clark) level 3 to get some geometry.
Make sure you're in solid view.
Enter edit mode and deselect all.
Use the box select tool to select some vertices.
Some random vertices are selected in addition to those: https://i.imgur.com/dcGWKBK.png

This bug affects solid, rendered (eevee and cycles) and lookdev view, but not wireframe. Might be related to #57770.

I can not reproduce this on my end. Could you see if you still get this problem with the newest blender beta?

Yes, I confirm that I still have it with today's build -7f77961f1c38; x86_64; 24 Jan; might be some peculiar combination of settings and OS (Ubuntu 16.04).
While rechecking it I noticed a pattern, faulty selects sometimes tend to be along lines. This is the default cube subdivided to a sphere, with only a single circle select on its left side: https://i.imgur.com/b5azdDy.png As it can be seen, faulty selects are conspicuously only on its top and left side, and only along parallel lines, in a seemingly semi-random distribution.

Okay, this is getting interesting: there certainly is a pattern, and selecting one side doesn't trigger the issue at all:

Are you using the latest nvidia drivers? (417.71)

Does this happen if you change the Selection method in blender preferences? (You could try to turn on opengl depth picking).

I'm running linux myself however with an AMD card and I don't seem to have any of these issues.

Updated to the latest available driver for OS and card combo (415.27, was maybe 381) and turned on opengl depth picking to no avail. Tried turning off multisampling to no avail either.

And this isn't a problem in 2.79?

Toyed for a while in 2.79b and couldn't reproduce it.

Additional information: when selecting individual vertices, sometimes they're not selected, but another one; that is, it's always one vertex that's selected, but it may or may not be the correct one. So it might be related to #60906

I'm also experiencing this issue and affects selecting faces and edges too. However, I noticed it only occurs when "x-ray" mode is disabled - try turning on Xray as a workaround.

OS: Win7 64bit
Blender version 2.80 (Date 2019-03-08 01:37, Hash oba143a1d675, Branch blender2.7)

I too experience it with selecting faces and edges, however with some pecularities:

When selecting individual faces, everything is fine. The issue appears only when using box select or circle select.
When I switch to front view or left view on a subdivided default cube and try selecting individual vertical edges, everything is fine. However I can't seem to select individual horizontal edges (hardly anything ever is selected, and when it is, it's the wrong edge). Again, box select and circle select are wacky.

I've been trying to trace the issue to the commit it appears in, but I'm having troubles compiling early revisions of the 2.8 branch. The issue dates back to at least f71efafe8f (on 31st of May last year).

@kineticwasepic Are you using version 2.80, branch master, or version 2.79, branch blender2.7? Could you share some more information about your system and setting, perhaps we could find some potential culprits?

Thanks about mentioning xray, I had forgotten it. However, sometimes I'd like to select just vertices on the near side of the object.

@DNCLCFW I'm using blender 2.8, downloaded just the other day from the official download page (not built from source). I've attached my system-info.txt, hope that helps. Also, this issue is not present in blender 2.79. system-info.txt

Can you test with latest beta? There was a fix about misaligned texture reads that were committed recently.

I tested it for a while with adfdae3fc2 / 26th of March build and couldn't reproduce the bug. Let's see what @kineticwasepic says.

I figured out how to fix this problem
step 1:
download this file
https://files.fm/f/kyyyc7y72
step 2:
go to folder :
C:\Program Files\Blender Foundation\Blender and paste the file you just downloaded here
step 3:
Let's see if the problem has been fixed

NOTE: i used blender 2.79 to fix this problem, you can download the latest version to fix the problem if the above doesn't help
