Actually this doesn't seem to be related to switching tabs only, but to all mouse events. It doesn't matter where I click the event seems to be delayed and as such causing the UI to show the lags.

Here the stack:

```
mozilla::layers::APZCTreeManager::GetTargetAPZC(mozilla::gfx::PointTyped<mozilla::ScreenPixel, float> const&)
mozilla::layers::APZCTreeManager::ReceiveInputEvent(mozilla::InputData&)
{virtual override thunk({offset(-16)}, mozilla::layers::APZCTreeManager::ReceiveInputEvent(mozilla::InputData&))}
mozilla::layers::APZInputBridge::ReceiveInputEvent(mozilla::WidgetInputEvent&)
nsBaseWidget::DispatchInputEvent(mozilla::WidgetInputEvent*)
-[ChildView mouseUp:]
...
```
