Undo Visual Glitch

Leticia Garcia's Photo Leticia Garcia 16 May 2022

Since I updated to NanoCAD 22 I've bee nhaving issues with the Undo command (CRTL + Z). When I do it repeatedly it causes a visual glitch in which things just desapear on the screen. I haven't noticed any pattern to what desapears, it can be lines, blocks, hatches etc.
The good things is the information is still present int the drawing, the bad things is it's really incovenient as I have to hit save, and reopen the drawing so things appear where they should.
I thought it could be related to RAM, so I have tried a few things like closing programs and only opening CAD, and also paying attention to what process are running in the background but so far nothing.
Seriously considering going back to 2021, it is annoying to the workflow.
Does anyone have any ideia of what it could be? or any kind of solution?

Win 10
AMD Ryzen 7 3800X
64GB RAM DDR4 3200mhz
RTX 3060

Thanks in advance :)

Maybe video performance test'll help a little.
You can run it - "Manage" - "Tests" - "Video Performance Test".
64GB RAM is more than enough, if I'm not mistaken.

This issue repeated sometimes and reason might be in damaged or polluted dwg, so I've asked tech support and they recommend to try this steps: https://forum.nanocad.com/index.php?/topic/1607-undo-visual-glitch/
