Double panel open after single click in keymap preferences
Confirmed, NormalPublicBUG


System Information
Operating system: Linux-5.4.0-66-generic-x86_64-with-debian-bullseye-sid 64 Bits
Graphics card: GeForce RTX 2060/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 460.39

Blender Version
Broken: version: 2.92.0, branch: master, commit date: 2021-02-24 16:25, hash: rB02948a2cab44
Worked: Even 2.93 alpha has this bug

Short description of error
Wrong operators panels config opens when clicked on key modifiers button in configure dialog.

Does not matter which panel is open in Sculpt, after click the last panel from Mesh opens. I pictured this on some screenshots.

Exact steps for others to reproduce the error

  1. Open Preferences Window.
  2. Navigate to Keymap.
  3. Search for "sub" name. A number of subdivision keystrokes will show, all those with Ctrl+1, Ctrl+2 etc. keystrokes. They add subdivision modifier to a mesh when pressed.
  4. Set up every Subdivision Set for Object Mode to be Alt+number instead of Ctrl+number.
  5. Then, collapse all those panels.
  6. Open first panel for config Scult -> Subdivision Set, this for Ctrl+0 keystroke.
  7. Click on Alt button. It toggles, BUT at the same time, a panel from above section (Mesh) opens!!!

Just to make sure: Please try with File → Defaults → Load Factory Settings to see if you still can reproduce this issue.

Yes, I can confirm the problem exists.

Exact steps I preformed are the following:

  1. Run Blender, load factory settings.
  2. Open pref window, navigate to keymap, search for 'sub' - they will be two sets of commands: for Object Mode and for Sculpt, all named 'Subdivision set' with different keyboard shortcuts, like Ctrl+1, Ctrl+2, etc.
  3. Unhide Subdivision set located below Sculpt for Ctrl+3, change it to Ctrl+Alt+3 - it may nothing happen, BUT previously it opened top panel for the same keystroke from Object Mode (they were reconfigured first in the previous tests).
  4. Hide this Subdivision set.
  5. Unhide Subdivision set below Object Mode for Ctrl+2
  6. Click on Alt or Ctrl
  7. Immediately lower panel with the same original keystroke opens and both are now configured as pressed.

This seems like panels are reacting to the same configuration input change (?) and reveals themselves because the change is messing with both places maybe?

This is stable and repeatable. If all but one panels are closed, I can click on Alt or Ctrl in the only open panel, and then corresponding panel from the other section opens. However it do not change, it just opens.

I've tested the last Blender 2.93.0 8f2c3c63e970.
The problem is still there. I've recorded and included a video showing the problem. All after 'Load factory settings'.
First change in panel WORKS. Further changes do not work properly (additional panels are opening) but this time their behaviour is not synchronized at all and seems a bit random. For example, when I click Alt or Ctrl in panel for Ctrl+2, another panel opens for Ctrl+4 or so. This is also visible on the movie.

Just another observation:

  • when all top subpanels for Object mode are collapsed, and all subpanels for Sculpt Mode are open...
  • ... clicking on any single Alt/Ctrl button force ALL subpanels open!!! That's the thing I could call unexpected and now this is a bit annoying.

Please look into this, it's not critical, but may be caused by some kind of bug which affects other places too.

Germano Cavalcante (mano-wii) changed the subtype of this task from "Report" to "Bug".

I confirm that an unrelated panel expands after the change.
