When wxWidgets is compiled with egl, glew needs also be compiled with egl support.
Is this done?

PS: I assume you have built Hugin with -DUSE_GDKBACKEND_X11=on
(otherwise it would crash on Wayland.) So Wayland or X11 should not
matter, Hugin is forcing in this case to X11 internally.

  This is with Hugin version 2020.0.0 and wxWidgets 3.1.5. Some users
  have reported that just the Fast GL Preview doesn't show up while
  Hugin keeps working.

  When compiled against wxWidgets 3.1.4, everything works perfectly.

  When built against wxWidgets 3.1.4, Hugin works just fine, which makes
  me think that EGL-related changes in wxWidgets 3.1.5
  <https://github.com/wxWidgets/wxWidgets/pull/2038> may be a reason,
  but this is just a guess.

  Thanks for the great application, btw.
