here you are
The crash was indeed unrelated and has been fixed in the meantime.

The issue is still present in 2.90 alpha with latest mesa 20.0.7:

I found something: The trigger for this issue is material slot assignment!
Take our default cube, add two material slots (one is not enough), enter edit mode, assign one face to material slot 1 and a second face to material slot 2 - the second face vanishes! The material slots do not need to contain materials.
The additional geometry is only added to the sphere, so the shape seems to have an effect, too.

Retested rB22925d0dd31e after mesa upgrade from 19.3.5-1 to 20.0.4-1 and the artifacts are gone.

There is a configuration that works: Specular Lighting: off removes the artifacts. There is also a slight improvement by setting Antialiasing >= 5Samples as long as there is no interaction.
Also, setting Specular Lighting to "off" and deactivating "Load UI" in the file view allows to load the Spring splash scene https://developer.blender.org/T74791 without crashing.

No artifacts in wireframe view here.
Found it! This commit also caused the crash opening the Spring splash scene https://developer.blender.org/T74791
Found the origin of the crash. It is the same commit that introduced the solid view artifacts https://developer.blender.org/T74790

Unfortunately, it does not help.
The situation has worsened in the meantime: in my current build version: 2.83 (sub 9), branch: master, commit date: 2020-03-15 18:22, hash: rB22925d0dd31e there are additional artifacts and trying to open the Spring splash scene (https://cloud.blender.org/p/gallery/5d2607ee6b3001d49bab798a) crashes blender. Both new problems are also exclusive to my HD7770 system and persist even if I revert commit 56d6666689f7, so I will make new reports.
Do you think you may have to drop support for GCN 1st gen systems like my Southern Islands HD7770 in the near future?

Used git reset --hard 20605c4b515e to go back to "Modifiers: UVWarp modifier add invert vgroup option" (Tue, Feb 18) 20605c4b515e prior to the two GPU commits and that build works fine.
So, working in version: 2.83 (sub 4), branch: master, commit date: 2020-02-18 17:14, hash: rB20605c4b515e
Also can't redo on skylake with integrated intel graphics, so I think this is related to AMD graphics.

Thank you for fixing it!
I still don't understand why going back to older commits (using git reset --hard <commit#> and rebuilding) did not get me back to a working state. I used make clean, even deleted the whole build directory once, it did not help. Perhaps I made something wrong.

Also resolved https://developer.blender.org/T73400
Seems to be resolved by https://developer.blender.org/rB3ba5461af0c8b1273d3daf87d050c24a690273be, so I updated the status

Thank you, guess I will have to wait two weeks until it lands on Manjaro, too.
Solved on Manjaro as well as of 16.1.2020 (upgraded to Mesa 19.3.2-2)
On manjaro stable, the latest Mesa is still 19.3.1-1 from 18.Dec 2019.
What version of Mesa solved it?
seems fixed in 2.83 (sub 0), branch: master, commit date: 2020-01-13 11:16, hash: rBa60606e4678a

Guess you are one of the lucky owners of older AMD graphics as well?
I bypassed the problem by downgrading mesa. Also Blender 2.79 https://download.blender.org/release/Blender2.79/latest/ is still working (but segfaults opening 2.82 projects). Those are no solutions in the longer term, but at least we can continue our projects.

Still present in 2.82 (sub 2), branch: master, commit date: 2019-11-27 20:26, hash: rB4659fa547166
Also happens with active backdrop (closed render window).

Confirmed the bug in Ubuntu 14.04 x64, same machine, 2.74RC1
The background image will reappear when panning the view down towards the center of the scene

This also happens with BI viewport rendering
