[User Interface Settings to adjust the black background.]

Thank you, I see what you mean.  That is really helpful..

[User Interface Settings to adjust the black background.]

Many thanks for this. Opening a  blank document did the trick.  Now I have another problem trying to bring a symbol object to the front. The drop gown menu with "Bring All to Front is  greyed out as is also the Arrange menu. Can you please rescue me again ?

See below

[User Interface Settings to adjust the black background.]

I am unable to change the black background setting which is very uncomfortable for my eyes. I have been going to the Affinity Designer Logo/Settings/User Interface and tried adjusting the sliders on the Background Grey Level and the Art Board Background and restarted my machine but nothing is happening, Can  you help? I am using a MacBook Pro with an M1 chip with Ventura 13.4.1  and Affinity Designer 2.2.1 Eula.

I would be really grateful so some help with this,
