System Information
Operating system: Linux-5.10.26-1-MANJARO-x86_64-with-glibc2.33 64 Bits
Graphics card: AMD Radeon RX 5700 XT (NAVI10, DRM 3.40.0, 5.10.26-1-MANJARO, LLVM 11.1.0) AMD 4.6 (Core Profile) Mesa 21.0.1

Blender Version
Broken: version: 2.93.0 Alpha, branch: master, commit date: 2021-04-13 20:36, hash: d63b72e9f9

Short description of error
The program freezes for ~12 seconds trying to display boolean geometry node result.

Exact steps for others to reproduce the error

  1. Download .blend file
  2. Connect "Boolean" output geometry node with "Group Output" input geometry node
  3. Freeze (100% CPU)

Thanks for the report.

In this case I think the boolean operation is just extremely slow for some reason, because it does unfreeze after a bit for me.
That shouldn't be the case for such a simple situation though-- there are only 2000 output vertices, so I'd lean toward calling this a bug.
But I'd understand if another developer wanted to call it a "performance improvement request" also, which we wouldn't keep on the tracker.

It's only a guess but this might have been fixed/improved by 28bf1d4037. Can you check it again?

Okay, thanks. @erik85, would you like to look into what's the bottleneck here?

Going to make this a known issue, since I don't think we'll have to time to look into it soon. Of course anyone is still welcome to look into what the bottleneck is here.

@HooglyBoogly did you try this again? I can't reproduce it now.

Ah, no I didn't. But I can't either, even when I change the node tree (removing the realize instances node added in versioning).

I'll go ahead and call this resolved then.
