Appearance of guideline deteriorated in Archicad 26



Guide Lines in Archicad 26 are appearing in manner where the white dash line is not coinciding with the coloured dash line.

However, in Archicad 25, it seems just fine (the white dash lines are creating a subtle background for the coloured dash lines).

Not sure, how it is appearing on windows version. I am using Archicad 26 (as well as 25) on macOS Monterey, using m1 max MacBook Pro.

In my opinion, it's a bug and should be addressed.

Dear Sharma,


Thank you for sharing this issue with us!


I checked on my Windows machine and I wasn't able to reproduce this error.
My first thought was that this might be happening because of some resolution settings. 
May I ask you to check that on your machine? 


Looking forward to hearing from you!

Kind regards,

Perhaps your antialiasing setting is turned off? See:

Many thanks!!

It had indeed solved the problem.

The horizontal and vertical guidelines are working normally but the angled guidelines are drawn in white, which makes it difficult to see them. Am I missing a setting somewhere?
