Substance Painter: Texture Island Bounds MESS

Hello.

I have been using Substance painter since 2017 and never once experienced the following issue:

The brush "Shahn" which is set to jitter by default is creating a massive mess. And so do most of the others (!). For some reason when going over a texture island into the next, the brush flips randomly into another direction and messes up the stroke direction. Also jitter brushes do NOT correctly transfer over the seam into the next Island. 

Please watch the video and follow what the brush does (switching angle and strokes don't transfer properly):

As I have mentioned, this was never like this before when I last used the Software in mid 2021.

Is it somehow possible to download the earlier builds (the one with the "Dragon Splash Screen")?

Currently it's unusable

Thank you.
