Cura 4.8.0 | Not Responding, Lags

[LordDamocles 0]

Hi All, I recently updated Cura from 4.0 to 4.8, now everything is slow. Opening .stl's, changing slicing values / settings, slicing and even just closing the program can either stall or start to not respond.

 

Similar to this thread, however the adjusting screens didn't change anything.

 

I am running Windows 10 Home 20H2

• CPU: AMD Ryzen 5 2600 Six-Core 3.40GHz
• Ram: 24GB (2x4GB, 2x8GB) Kingston DDR4 2400MHz
• GPU: NVIDIA GeForce GTX 1660
• MB: MSI X370 SLI PLUS (MS-7A33).

 

4.0 worked perfectly.

 

Thank you.

I also started having the same issue recently with Cura 4.8. I have plenty of CPU and memory; never had an issue with Cua before this version. Every 30 - 60 seconds the Windows window says "Not Responding" and it will freeze for at least 10 seconds doing almost anything, like adjusting an object's placement, rotating, scaling, slicing, etc. Cura will keep freezing and I'm not sure why.

Cura regularly searches for lots of things.  For example you could just see what happens if you:

1) disconnect all network connections.  

2) Remove all (or all but the mouse?) USB devices

3) disconnect from network drives, usb flash drives, uSD cards, and other drives other than the primary hard drive.

4) Also if you have multiple monitors try disconnecting one of them.

 

I read stuff about things that helped other people but my memories are vague.  But some of them are things similar to the list above.  For example If you plug any USB device it tries to see if it's a printer and can cause cura to crash or just be very very slow.
