Blender 4.2 Issue

Blender 4.2 has an issue with the redo panel not redrawing or refreshing correctly when calling back the redo panel using the F9 hotkey in the viewport. See how the F9 hotkey works in connection to Blenders redo system here if you are not familiar with it yet.

Figure 1

Figure 1 shows the redo panel acting correctly as as the viewport is not moved, panned, rotated or zoomed.

Figure 2

Figure 2 shows the redo panel issue when the viewport angle has been changed and the redo panel called back using the F9 hotkey, enabling any of the dropdown sections no longer changes the UI.

If you are using Blender versions pre 4.2 like 4.1, this is not issue. However, to solve this for 4.2 until a fix for this has been made by the devs, you can enable the Use confirm or Ok redo panel in the add-on preferences.

Figure 3

This will make the add-ons popup menu into a confirm type. You will only see live changes when you press the OK button to activate the script.

Figure 4

After pressing the OK button, the menu will disappear and you can call it back using the F9 hotkey but in order to avoid the issues mentioned above, you need to access the redo panel in the bottom left area of the 3D viewport.

Figure 5

This panel will stay docked and will not disappear even if the mouse cursor moves outside the menu.

Figure 6

With this, enabling the drop sections will change the UI but there is still some problems like toggling on one of the sections will enable a different one although it is workable now.

Simple conclusion, use Blender 4.1 for now if you are using Random Starship but if you want to use Blender 4.2 then you can try the temporary solution above until the problem gets fixed inside Blender.
