Setup: Windows -> WSL Ubuntu -> Docker The first time I've started a project, it worked correctly. Second time, it cannot find the display for an unknown reason, as the container is executed with XAuth passed, and even in privileged mode it fails.
Project: Cutter docker dev build
qt.qpa.xcb: could not connect to display
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.
Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, xcb.
