This application failed to start because it could not find or load the Qt platform plugin "xcb"
Running bitmask from the bundle on debian sid I get the following error:
This application failed to start because it could not find or load the Qt platform plugin "xcb".
It looks like the bundle is missing libqxcb.so. I have this library in my system, but might not be compatible:
ii libx11-xcb1:amd64 2:1.6.4-3 amd64 Xlib/XCB interface library
