SpTabLayout causes errors when switching Pharo theme #1632

Open JanBliznicenko opened 1 month ago

JanBliznicenko commented 1 month ago

Whenever a window with SpTabLayout is open (or even closed, but still in memory), Pharo theme cannot be changed, or changes just paritally, and ends up in an error.

Example:

| previousTheme newTheme |
Smalltalk garbageCollect.
SpExampleBrowser open.
previousTheme := Smalltalk ui theme class.
newTheme := (previousTheme isKindOf: PharoDarkTheme) ifTrue: [ PharoLightTheme ] ifFalse: [ PharoDarkTheme ].
newTheme beCurrent.
previousTheme beCurrent.

Confirmed the issue to be present in all versions of Pharo (tested in 11-13). In Pharo 13, use build 299 or earlier, as there is another issue at the moment, preventing the SpExampleBrowser from opening, since build 300 (https://github.com/pharo-spec/Spec/issues/1631).

Tested on Windows 11.
