The flameshot(screenshot app) crashed

[Chuanhuan]

When I'm using vnc, the flameshot works perfectly.
Just wonder why the flameshot will crashed every time on xserver-xsdl.
Any help will be appreciate. Below is error message.

QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-root'
flameshot: error: Unable to connect via DBus
qt.qpa.xcb: QXcbConnection: XCB error: 146 (Unknown), sequence: 184, resource id: 0, major code: 139 (Unknown), minor code: 20
[1] 335 segmentation fault flameshot

I think I have same XCB error:146 issue might cause from qt:
#129
