SUMMARY When decreasing the window width until the sidebar gets hidden, while a channel's QR code is being shown, kills the UI interaction completely. STEPS TO REPRODUCE 1. Open the sidebar of a channel 2. click on the QR code to display it in fullsize 3. decrease the window width until the sidebar gets hidden OBSERVED RESULT As soon as the sidebar gets hidden, no interaction with the UI is possible anymore, clicks get just ignored. This terminal output coincides with the UI getting broken: > QQuickItem::stackBefore: Cannot stack QQuickRectangle(0x2f2edba0, parent=0x25e055a0, geometry=0,0 0x0) before QQuickPopupItem(0x25d66d00), which must be a sibling A restart is needed to be able to use Neochat again. EXPECTED RESULT The UI doesn't break when resizing it while displaying the fullsize QR code.

I'm getting the > QQuickItem::stackBefore: Cannot stack QQuickRectangle(0x2f2edba0, parent=0x25e055a0, geometry=0,0 0x0) before QQuickPopupItem(0x25d66d00), which must be a sibling message when resizing the window also when no QR code is shown. The message being logged coincides with a brief freeze of the Neochat window for ~1 second.
Hi - I can confirm this on my Fedora KDE 41 device. Thanks for your bug report! For what it's worth - maybe this could be related to https://bugs.kde.org/show_bug.cgi?id=471137 ?
