I have installed Affinity Designer V1.6.5.135 on a new Windows 10 Pro PC running a new Radeon RX850 graphics card with DirectX12 support.
At startup Affinity Designer displays a dialog starting with the following text:
Windows Version 10.0.17763.
Radeon software version 19.1.1.
I assume that there is some problem with Affinity Designer DirectX version detection. Is there a new version of Affinity Designer available which corrects this issue?
