#17331 (Bug) Strange doubling of windows in Linux

I’m using DisplayCAL on elementary OS 5.0 system (Linux, Ubuntu-18.04-based) with NVIDIA GTX 1080Ti video card.

The application seems to work fine, but for the reasons unknown, all its windows look as if they were doubled and inserted into one another, or maybe framed into itself (see pic). Every DisplayCAL’s window has this double-framed look.

The  logs  are in the attachment.

I hope you’ll find the answer to this visual mystery,

Thank you,


double window

  1. Hi,

    not fixable by me:

    #!/usr/bin/env python2
    import wx
    app = wx.App(0)
    f = wx.Frame(None)

    Please report upstream to python-wxgtk3.0 package.

  2. Other applications are affected as well. For reference: https://github.com/elementary/gala/issues/244

    Seems like the underlying issue might be in GTK: https://gitlab.gnome.org/GNOME/gtk/merge_requests/566

    A workaround is available: https://github.com/elementary/gala/issues/244#issuecomment-452695835
    This workaround will also be in the next minor DisplayCAL update (although not in the desktop files, but in the main.py), so even if GTK change doesn’t get merged it should still work.
