Re: [orca-list] gtk3-1:3.24.24: terminal problems with orca

[Alex ARNAUD <aarnaud hypra fr>]

    Hello all,
    
    Thanks Alexander for reporting this.
    
    I reproduce the issue, it's the flat review of Orca which no longer
    works on Mate Terminal.
    
    I reproduce both on Orca 3.36 hypra version and master.
    
    As I don't use flat review I don't have tried on Mate Terminal.
    
    Best regards.
