CubicSDR (Ham Radio panadapter spectrum visualizer using inexpensive receivers) upstream moved to wxWidgets 3.1 over 18 months ago.  While I had some success in backing out some specific changes that let it compile with wxGTK 3.0, upstream has moved on considerably since then, making extensive use of wxGLAttributes in various calls, which is far harder to back out.  Furthermore, upstream won't look at issues on older releases. [1]   Lending some urgency are multiple abrt-reported segfaults, including on F30 and F31 [2].  Either a wxGTK 3.1 package in the main repos, or in copr, will be needed to make this package usable again.
