As far as I have been able to test, up to version 2023-104 it Works correctly.

I have updated my graphics drivers and the same problem persists.
The funny thing is that by reinstalling versions 2011.111 or version 2023.101 the problem disappears.
It only appears if I install version 2023.106 or versión 2023.107

When the program is in full screen, a strange vertical line appears on the screen. This has never happened before.
I Have a Wacom Cintic 24""

Effectively, Ai automatically chooses the best possible quality for the type of paper chosen.
I have Let printer/driver manage color option selected
I have an Epson 2750. This is, effectively,  the case, except if I choose the normal paper type  and the quality that I want, AI automatically changes it to draft quality. (??) no the best quality.

Thanks for explainng how to desactivate ai.

I am having problems with ai.
How can I print a photo at the quality I assign without Ai deciding the quality she wants?

I select the printer drivers to control the color management... In the printer configuration dialog I select the type of paper (normal) and the quality that I want. Ai decides for me and sets the printer to print in draft quality always.Why?

Is it possible to disable the ai?

Solved
I don't know what the problem would be but uninstalling the app and reinstalling it fixed it.

Since the last update this error occurs when I try to close the program:
I get the following error message:
"C:\ProgramData\ddisoftware\Qimage\sabe\{Q}startup.jst could not be saved. Write Access denied."

In the menu "Utilities / Photo editor setup..." I have select Affinity Photo as my external photo editor
If in a thumnail, I right click an select "Edit image(s) option the image is edited in the Qimage default editor and no in Affinity Photo.

How can I edit an image in Affinty photo from qimage directly?

I work on a 24 inch 4k screen.
Is it possible to make the preview view occupy the entire area of ​​the preview screen.?
Working with a 4k screen has the advantage of being able to see things more accurately. But at least in the trial version it is not possible to increase this preview view to have a more adjusted (enlarged) view of the page.
