Flashing in 3D modeling views

Gus — Mon, 16 Nov 2020 19:45:41 GMT

When I try to navigate (rotate, pan zoom, etc.) in 3D modeling views, it flashes my site plan. It's not the end of the world, but it is extremely annoying every time I'm working in any 3D view. Does anyone know why it might be flashing like this?

Hello Gus,

Do you model near the origin ?
Do you have two elements at the same place ?
Can you share a screen capture ?

The first thing to do when you see some graphics anomaly is to make sure you have the latest graphics drivers on your system.

Is this the flashing you get?

I've recently noticed this in 3D views...

I noticed this during Beta testing for 24 and reported it at the time.
You will get a quick flash of whatever is in your 2D window.

I can't recall the outcome, and we don't have access now to the Beta reporting.

It doesn't seem to affect anything - just a little annoying.

Barry.

I've started experiencing exactly this in 25 v6000. I assume it's a hardware issue but was there any conclusion to this?

Is your Editing Plane display on? That has caused some screen flashing or flickering for me in the past.

No, it happens with or without the editing display

This has started to happen to me across multiple versions of AC (our office uses 22-25). I was able to record this for AC 24 but it is persistent in those I have tested. Additionally, if a change is made to the view settings of the 3D window, it will jump to the last active 2D window almost like it is trying to regen.

Video of issue

To squash any questioning replies: yes my drivers are up to date, all system updates are in place, and all peripherals are updated as well.

This was not always the case for this specific computer, but we are in the process of testing how Windows 11 works with ArchiCAD as commercial sales are ending for Win 10 and support is dwindling across multiple platforms. This did start happening with the Win 11 upgrade but according to Graphisoft, they are supporting AC versions 25 and up for the Win 11 transition. It is unacceptable to have graphical lag impact performance and efficiency.

Has there been any fix for this? Are there even any constructive thoughts from GS? Has anyone heard anything other "update your drivers" from GS?

Any help would be greatly appreciated.

Dear Nathan,

I had exactly the same issue and I had a hard time concentrating.

I finally solved it by uninstalling Archicad, but using iobit uninstaller.

The difference with uninstalling from windows settings is that iobit uninstaller erases everything, including registry records of the application.

I installed it again and it works great.

To add to my previous reply,

The problem seems to be caused by the 528.49 NVIDIA drivers.

I had the 516.49 installed (clean install) and the problem disappeared.

Hope I helped.

I am noticing this with 26 5002. I have reinstalled windows and still this is happening. Latest NVIDIA drivers with a 3080Ti.

Also when I am in 3d and click the floorplan windows everything disappears. The flooe plan is white. I have to scroll or double click for the elements to appear.
