Hi all, wondering if anyone is having a similar problem. I'm using Archicad 25 SPA, and specifically on an Apple iMac with a 5K screen if I draw any guide line in an orthogonal direction (pure horizontal or pure vertical) they appear as they normally should, in the dashed orange color. However, if I draw any guideline in any angle they turn invisible. In reality, they turn kind of white, so they are not visible against a white background. The interesting part is that the guide lines are there, so If I change the background color on the screen, they appear, but in a different color, they show kind of pink or light violet.
What's even stranger is that this happens only specifically on the 5K iMac. I tested the same thing on a 2020 MacBook Pro and the guide line behavior is normal, where any guideline at any angle shows in the normal orange dashed line. I then tested again on a PC computer and also the correct behavior. I had one of our staff architects test on her 5K iMac (slightly older model) and the behavior is also normal.
I then proceeded to uninstall Archicad and do a fresh install, but the behavior is still the same on my particular 5K iMac.
I've come across Archicad bugs before, but this is downright weird !

Have you tried updating your graphics card drivers?
You could also go to the "Advanced Redraw Options" page of the "Work Environment" Dialog, and check whether changing the state of the "2D Drawing Antialiasing" checkbox or the "2D Drawing hardware Acceleration" slider change anything. These are setting that can influence Floor Plan Display.

@Laszlo Nagy here is a mystery for you.

I’m experiencing the same problem.

Hi Laszlo, good observation. My results:
For now, my solution will be to keep 2D antialising OFF and keep hardware acceleration ON.
Since I'm on a Mac computer, I can't update graphics drivers, but my system is current to the latest OS update, so this should have the latest graphics drivers updates.
Thanks for the idea, at least this gives a solution for now... but this seems to be a bug specifically related to iMac 5K systems.

I am glad that unchecking the "Antialiasing for 2D drawing" checkbox corrects the problem.
I will report this to Graphisoft.
