Describe the bug
When adding a widget to a container.NewThemeOverride, the widget and its override theme are stored in the overrides map. This is never cleaned out except when a window is closing. This is because the deletion of the widget's entry in the overrides map happens in cache.DestroyRenderer, but that function is only called when a window is closing. Elsewhere (eg in the regular clean task), renderers are directly destroyed instead of by calling this function, which misses the deletion of the entry from the overrides map, if that widget had a theme override.
How to reproduce
just check the code as described above. Or create an app that cycles through new widgets, applying an override to them, and then not using them. It will leak memory
