Description phoenixrising656 2023-10-02 06:19:24 UTC

Steps to Reproduce:

Launch Dolphin file manager on KDE Plasma desktop
Navigate to any folder with file/folder contents shown
Try to change to a different folder (This bug occurs sporadically.)

Expected: Dolphin transitions smoothly to new folder view

Actual: Dolphin hangs/freezes in the process of changing folders

Logs indicate Qt/XCB BadWindow errors occurring during the freeze:

02/10/2023 11:45 AM kwin_x11 qt.qpa.xcb: QXcbConnection: XCB error: 3 (BadWindow), sequence: 28982, resource id: 111149067, major code: 18 (ChangeProperty), minor code: 0

02/10/2023 11:45 AM kwin_x11 qt.qpa.xcb: QXcbConnection: XCB error: 3 (BadWindow), sequence: 28986, resource id: 41943175, major code: 18 (ChangeProperty), minor code: 0

Qt's XCB module failing to properly handle window IDs during Dolphin's folder transition likely causes the freeze.
