Scanning in color does no longer work on Big Sur (only in BW)

[Aymara]

Hi,

since the latest update I can only scan images in black & white. When scanning in color, the result is garbage.

Scanning with Apple's Preview app though still works fine, so it's an Affinity problem only.

Furthermore it now takes ages until Affinity Photo starts.

My system:

iMac Pro 2017
macOS 11.6.1
Affinity Photo 1.10.4
Canon TS 5050 (Printer / Scanner Combo)

Attached a color scan example, one intact by Preview App and a corrupt one by Affinity Photo.

Problem solved (start performance and scanning) after opening the scanner from the system preferences.

Strangely that was never needed before after an update.

 

PS: It might be worth noting, that my user account is not a member in the sudoers group. For security reason's I have a separate admin account.

Hi @Aymara,

Many thanks for letting us know you've been able to resolve this issue!

Our developers are aware of a few issues whilst using metal hardware acceleration on certain macOS systems and I suspect this was possibly causing the scanning corruption within Affinity.

We hope to release an update shortly to address this corruption, so I should hope you do not experience this again in the future
