Archicad 26 2d problem

[Y100F]

Hello, recently we faced a problem after installing Archicad 26 int.

The case is:

In 2d window if we enable trace reference and pick up a Wall Tool with ( Alt+C), when start drawing a wall, there is heavy lag , which makes impossible to finish the desired wall. Meanwhile the drop menu for the wall parameter-building materials is blinking in unusual way. 

Any suggestions way is this happening and how to resolve this?

Thanks in advance.

We`ve got several licenses and this bug is in all versions of A26INT, including the 4004 int.

All videocards are quadro`s like p4000, p5000 , and one RTX3060 12gb. same thing everywhere.

Same problem here, A26INT, update 4019. Also happens only when I activate trace reference. And it happens only with basic walls, when selected. Composite walls behave normal.

I have not noticed any issues, but that is not to say that there isn't.

What are you using as your trace reference?

Is it a view point from the Project Map, a view from the View Map or a layout?
