Short description of error
Viewport in the shaded mode looks considerably worse in the newest builds, lacks anti-aliasing.

Older build:

Exact steps for others to reproduce the error
The issue should be evident after opening the attached file.

What I tried

Deleted the Blender's settings folder
Set the Viewport settings to maximum quality
Tried on another PC
Shared the file on the Discord channel, another user confirmed:

Seems like it was b52a0c78af that broke this.

There has been a change in the design of the viewport quality and anti aliasing in general.

Every scene can set its anti aliasing method for the viewport and for rendering. This can be done when switching to the Workbench engine and then change the settings in the render sampling panel.

By default the viewport anti aliasing is set to Single pass anti-aliasing as the viewport should be as fast as possible. We cannot consistently determine the correct setting when loading older scenes (Viewport Quality is user setting, Viewport and Render samples are scene settings; this will lead to different result based on the user who loads the file), hence we set everything to the default values (Render: 8 samples, Viewport: Single Pass Anti-Aliasing) .

When you have a machine that is slower you want to have a setting to limit the viewport quality. This is the Viewport Quality setting in the user pref. This viewport quality setting only limits the Anti Aliasing samples if the setting in the scene is higher and only for drawing in the viewport. It will not change the anti aliasing method when saving the file.

During Viewport Render Image or Viewport Render Animation the Viewport Quality setting is not used.
When doing Render Image or Render Animation the Anti aliasing is used of the scene.

We have updated the manual to reflect these changes https://docs.blender.org/manual/en/dev/render/workbench/quality.html

Thanks for explaining this. It all makes sense now. An update to the View Qalityality setting tooltip, as well as Multisampling settings would help, however. By the way, the maximum Multisampling setting in the User preferences is 16 samples, and you can set up to 32 samples in the Scene settings, but how does it work together if the settings in the User preferences override the Scene settings when the Scene multisampling settings are higher?

Shouldnt this option be in the solid mode pop-up rather or in addition to it being in the workbench render settings?

Having to change the render engine to configure something related to the viewport seems a bit awkward to me...

Cheers.

Completely agree. That's the second place I checked when I realized the AA was gone (The first being the Viewport tab in the User preferences).

@WilliamReynish any input on this?

Yes, I agree this seems weird. We don't do it this way for any other viewport setting that applies to Solid mode - you don't have to switch to the Workbench engine to adjust.

When just using Solid or Wireframe view, we should set the AA quality with the Multisampling setting in Preferences

I think it's clearly a bug that the workbench render settings affect the viewport, this should be controlled by the preferences. The Viewport Quality setting in the preferences has no effect now as far as I can tell.

Ideally it would changed to a similar enum as the new ones for the workbench, since a 0..1 slider here is rather odd.

Setting the Viewport quality to lover values reduces the amount of anti-aliasing for me. Different Multisampling settings, on the other hand, don't seem to affect anything.

Will prepare the next changes:

Interactive viewport rendering will only use the user pref setting. The settings in the Sampling will only effect (Viewport Rendering/Animation and Render Image/Animation)
Viewport Quality will be replaced by a drop down list (Viewport Anti Aliasing)
