It will fire after slide is unloaded -> crash. And it might fire also when the EffectWindow for the Surface would get destroyed.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">I suggest to change it to something like:
connect(surf, &slideOnShowHideChanged, this, [this, surf] { slotThingy(effects->findWindow(surf); });</p></pre>

Seems in the end we did not add it?</p></pre>

onblurchanged directly takes the effectwindow from the captured context as well</p></pre>

<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">The connection could be stored as dynamic property on the window or alongside the other "Data" and disconnected when the window is deleted.</p></pre>
