Short description of error
It is very difficult to select a gizmo created with new_custom_shape
Exact steps for others to reproduce the error
Using default scene and the factory setting,
Change the power of the light to 0, to see the gizmo
open and execute the template gizmo_custom_geometry.py
Try to select the gizmo to change the power of the light. Sometimes, it is impossible to select.

While it's not difficult to select, there are times it flickers un-selected even though the cursor is still over it.
I don't know if it's only for me, but this how the gizmo looks like when I run the script and it's difficult for me to select :
@Clarkx - it's very different here, occasionally it flickers off, but it works most of the time.
Just for information, the selection is now working fine, thanks !, but the new_custom_shape function is not working for me with the 'TRIS' type option.
This is what the gizmo looks like using the gizmo_custom_geometry.py template and a point light :

Hi guys,
What is the status of this bug? I am trying to create an addon that requires new_custom_shape to work. I was looking at the source code but I can't figure out the problem. Could anyone point me in e right direction?
I don't understand how the gizmo is rendered properly yet our selection query did not identify it in the selection buffer. I tried to use renderdoc to extract the selection buffer but it is not shown in the render doc.
Thanks

Not changing status here, but script template doesn't seem to work and I have seen custom gizmos that work fine.
Hi @iss
I just tried on blender 2.82-18343c230d2c-windows64 and if the selection is still a problem, the shape of the gizmo is good and I was wrong.
Thanks a lot for your help.
@Clarkx I can not test that, because template script doesn't work.
Can you update report(description and title) to represent actual issue with file that works in 2.83?

Hmm I haven't any problem selecting it...
I changed UI scaling to see if it affects this, and "hot area" was quite off.
Do you have any scaling on display? did you try this on different PC? or if you create new user, to get fresh display settings?
Can't try on another PC, and it's the basic display settings.
I just download the daily build of the 2.83 version with factory settings, and I can reproduce the problem :
Now I can't select the the gizmo anymore.
Can you try gizmo in #73033 (Gizmo : "target_set_handler" doesn't show the tooltip description when the mouse moves over the Gizmo.) and tell how it behaves?
There is no custom gizmo in #73033 (the script is using the GIZMO_GT_arrow_3d gizmo) and it's working perfectly, no problem there.

@Clarkx are your GPU drivers up to date?
@lichtwerk Can you triage this? May be GPU issue, I am out of ideas.
It would be likely known issue anyway, but at least we would know what to fix.
@iss
Yes, I've download the latest nvidia driver (441.87) and the problem is still here for me.

Well, I can select it (occasionally), but it behaves rather strangely:

AFAIK this has always been an issue. Would be nice to see fixed finally but it doesn't seem like anybody is planning to look into this soon. Setting as known issue.

I still can't redo this, it's working reliably here:
Marking incomplete.

0330d1af29Hi, I tried with the latest version of Blender 2.90, and I still have difficulties to select the gizmo on Windows / GeForce GTX 1080 Ti : When big, the gizmo can be selected only on the center. But when the gizmo is too small, the selection happend even if the mouse does not touch it.
I've upload a test file with a square mesh with different sizes and a little video to demonstrate the problem on my side.
Thanks again for you time.

Can't reproduce this still either.
@Clarkx Can you update GPU driver and re-check? 441.87 would be probably 6 months old.
Hi,
I've updated the drivers : Graphics card: GeForce GTX 1080 Ti/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 456.38
But the result is still the same :
@Clarkx thanks for the update, tested and it's still working properly for me.
Well really sorry to wasting your time, I don't know what I'm doing wrong here..
Anyway, thanks a lot for trying.
@Clarkx not a waste since it seems you're not the only person with this issue.
@lichtwerk can you still redo this bug? if so would you be able to look into this since it makes gizmos not all that reliable.
I can redo in 2.90 release, but this seems to have been fixed by the stream of GPU refactors in 2.91 (
efc97b3919specifically marked the end of this bug for me)@Clarkx : could yo check if a fresh 2.91 build from https://builder.blender.org/download/ fixes it for you, too?
Indeed, it is way better with the latest build : 2.91.0 Alpha, branch: master, commit date: 2020-09-16 21:05, hash:
27660b3cd9There is still some sort of boundary around the gizmo as you can see in the gif bellow : The gizmo is selected even if the cursor is outside of it, but maybe this can be change in the preferences, I don't know.
Thank you very much for your work.
Many Gizmos have this by default.
I think you could control/customize this with
draw_selectandtest_selecthttps://docs.blender.org/api/master/bpy.types.Gizmo.html
It is not totally clear how to use this (would have to dig deeper), maybe we can improve the documentation here.
But regarding this report, I think we can close this (since the selection margin seems to be intended behavior)?
Changed status from 'Needs User Info' to: 'Resolved'
Just a research note (if this ever comes into play again):
relevant functions:
wm_gizmomap_highlight_findgizmo_find_intersected_3dgizmo_find_intersected_3d_internIf
test_selectis not defined specifically, this seems to go over the selection buffer and checks with3 * U.pixelsizeas well as10 * U.pixelsizearound the mouse position if it finds the gizmo in that area.So the "margin" is defined here, lowering the value to
1 * U.pixelsize(and just provide one value) will give you a really tight selection/highlighting around your geometry.If you set up
test_selectyourself, you're getting the 2D mouse position as input and need to do the intersection test with your Gizmo yourself.@ideasman42 : we could possibly expose this "hotspot margin" to the python API (as an alternative to setting up the whole
test_selectroutine)?.In any case, this is more of a TODO, but not a bug. Will close this report now, since it all seems to work as expected now since
efc97b3919.Thanks a lot @lichtwerk ! I will take a look at the test_select function.
@lichtwerk having the radius was done gizmos that are made from thin lines / wire-frame, for solid shapes this makes less sense (although it could still be useful when zoomed out).
We could make this optional (per gizmo for example).
