QDBusViewer confirms that PowerDevil emits the correct DisplayRemoved signals, meaning no issues in the daemon internally related to this. So the next question was whether the applet will correctly receive these signals and update the display model. It turns out that the async nature of checkDisplayNames()/updateDisplayNames() in ScreenBrightnessControl is what causes this issue. In a nutshell, the change signals come in fairly quickly, and the use of QCoro means that another call to queryAndInsertDisplay() may be fired before the previous one had finished. I've got a fix for this, which bluntly rips out the use of async functions where display model changes are involved. Which is most of them, really. I'm sure there's a more efficient fix, but I'll stick to just making it correct for now. -- You are receiving this mail because: You are watching all bug changes.
