Having similar problem after updating to 2022. thought was a problem with graphics card but the driver is up to date.
The problem normally starts when modeling something small. but once it happens it goes to all the geometry.
Sometimes just drawing a line on a face is enough to see that line flickering.
Normally happens inside same group geometry.
I’m am running Sketchup 2022 Version 22.0.354 64-bit on Windows 10.
AMD Ryzen 9 3900X
NVIDIA GeForce RTX 2070
