wxGUI no longer shows start image

[neteler]

When starting g.gui in G78dev only a kind of empty frame is shown (really, some graphic memory garbage of the window behind if present) while it works ok in master.

Not reproducible on Fedora 30, please make distclean, check git status, then recompile.

I have the same issue reported in a freshly re-compiled grass-dev in Fedora 30 (I use make distclean).

I get this in the terminal when opening GRASS:

/home/veroandreo/software/grass77-dev/dist.x86_64-pc-linux-gnu/gui/wxpython/wxgui.py:101: DeprecationWarning: Yield() is deprecated
  wx.Yield()

Might that be related?

If I start in text mode, and then call GUI with g.gui, then the start image displays normally and with the same message as described above... so, no idea

At startup (using relbr78), I see these error messages:

/home/mneteler/software/grass78_git/dist.x86_64-pc-linux-gnu/gui/wxpython/wxgui.py:101: DeprecationWarning: Yield() is deprecated
  wx.Yield()

I can't reproduce on Ubuntu. Are you sure that it works in master? If yes, it shouldn't be that hard to figure out the specific commit causing it.

It's not error, just warnings and debug, I think I get these too, so they don't have to mean anything.
