When in a file open/save dialog and you want to change the icon view via right click or sorting or click the menu button top right to open the contextmenu it shows the contextmenu and then freezes everything. The menu cannot be closed anymore nor can an item be clicked on. So to reproduce. Set QtCurve Widget Theme in systemsettings. Open Kate -> File Open -> right click I tried it on older versions available on ubuntu / kde neon / debian / neptune Version 1.8 and the newest git version show the same behavior.
Cannot reproduce on Arch Linux, plasma 5.12.4, qtcurve-qt5 1.9.1.
@Dr. Chaptatin yes tested in on newer Qt version and there it does not happen. However it happens with 1.8 on Qt 5.7.1 (Debian Stable)
