I compiled qtbase from dev branch with debug info and when I start sddm it crashes with glGetString call
note that glGetString points to a valid memory address.
oh, I just realized I forgot to recompile qtdeclarative. Isn't there some way for Qt to tell that it's ABI related issue and need to recompile?
So now after recompiling qtdeclarative I get this
I'll submit new issue for that
