System Information

OS: macOS Mojave (10.14.6)
Graphic card: Radeon Pro 450 2GB

This error is also raised on Windows 10 system.

Blender Version

Broken version: 2.92.0 or later

Description of error

built-in shader 3D_POLYLINE_UNIFORM_COLOR in gpu module does not render correctly in the space other than View3D.
I made an add-on which reproduces this error.

3d_polyline_uniform_color_shader_issue.py

To reproduce this error, follow below processes.

Install the attached add-on.
Enable add-on (Add-on name is: Test add-on)
Go to Sidebar in View3D, and select Test Category > Test Panel
Click Test Op.
The rectangles are rendered on both View3D space and Outliner space, but the rendered line will be unstable when the mouse is moved (This behavior can be seen often when the mouse moves to the other space).
To stop rendering, click the mouse left button.

I will show you the example which the line is not rendered correctly.
The rendered line on Outliner space is not same as View3D.

Thanks for the report. Unfortunately the scenario described is too time consuming for us to track down, we require the bug reporter to narrow down the problem.
Scripts showing the error need to be as simple as the examples shown at: https://docs.blender.org/api/current/gpu.html#examples

The script needs the uniform "viewportSize" to be set.

e.g.

region = context.region
shader.uniform_float("viewportSize", (region.width, region.height))

The script needs the uniform "viewportSize" to be set. e.g. ``` region = context.region shader.uniform_float("viewportSize", (region.width, region.height)) ```

I am sorry I am very strong disagree with you because they said "CAN'T" No way. They did fix made it I can tell many years ago. I totally believe they can do fix everything as well. I am going show you on youtube. They can change code and match thickness line for Mac and Windows both.
Sculpting tab there error thickness line too.
See youtube.
