Blobs on curved surfaces on Cura 5.3 and Klipper

[Alesh 0]

Hi guys,

I would like to ask You for help with my issue. I have highly modified Anet A8+ printer with Klipper on it. I have been happily using Cura until now. I have recently upgraded to version 5.3 which have some features I like but I am facing strange behavior, You can see at picture attached. It is a top "ring" from this project - https://www.thingiverse.com/thing:45214. I can see the same issue on other models - on 3D Benchy for example. It is on curved surfaces only. I have tried to increase buffer in Klipper (buffer_time_high: 10) with no success. I have tried another slicer which don't have this issue, but I really like features of Cura. Could You please help me with solving this issue?

That looks similar to what is going on in this bug report #15001 on GitHub.  I don't run Klipper so I can't take a look.
