Short description of error
I installed the newest blender (2.81), and so far it seems amazing, but one thing irks me. In Eevee, the hair particles only work in strand mode. When I try to use strips, they disappear completely. Is there a solution to this issue?
Exact steps for others to reproduce the error
Set "Render Engine" to "Eevee"
Add hair particle system to mesh object
Set "hair type shape" to "strip" under "Hair" in "Render Properties"
EDIT: I ran the Blender via the "blender_debug_gpu_glitchworkaround" command script, and the hairs were able to display as strips. However, I still need to know how to make them work when I run the program from the default executable. I'll provide the debug output.

@fclem: I can see lots of
GPUShaderInterface: Warning: Uniform XXX not found!
Anything we can do here?
That's what I'm wondering myself. The problem is fixed temporarily when I run "blender_debug_gpu_glitchworkaround", but I'm just wondering how that can be fixed for good.

The uniform warning is just a warning. It's harmless.
I cannot reproduce on Linux+Intel/Nvidia. Maybe @Jeroen-Bakker can repro on AMD+windows.

Is this still an issue with latest build? https://builder.blender.org/download/
I don't know. Let me see.
UPDATE: Yep. the problem still persists.

What is the "blender_debug_gpu_glitchworkaround", also did you update your graphic card drivers?

No activity for more than a week. As per the tracker policy we assume the issue is gone and can be closed.
Thanks again for the report. If the problem persists please open a new report with the required information.

Hi, Has this been solved, cuz i'm getting the same problem and i need answers, thank you!
I wasn't able to reproduce bug in first place, so I don't know if there is anything to be fixed.
Please make sure your GPU drivers are up to date, download latest Blender version https://builder.blender.org/download/ and click on File > Defaults > Load Factory Settings
If you have problems after these steps create new bug report.
i feel dumb, i had this exact same problem, had the exact same graphics card, and the exact same issues as in this post: it used to work for me in 2.8 but no longer after 2.81, all i had to do to fix this for good, was to update my graphics card but i never thought of it until i read about it here, thank u all! i appreciate what u do.
edit:
and i guess yes, resolved.
