not sure but Prefs-EGL_Wrap is a wrapper from Huno which is supposed to work with Huno ports and nothing else.
AFAIK no other software/game besides the ones from Huno supports/uses the EGL-WRAP-LIB from Huno so my guess is that your problem lies somewhere else.
I think it is ok that your R9 280x is seen as HD7900 since AMD rebadged their "old" card and gave a new name.
I have a R7 250 and it is seen as HD7800.
