Photoshop sometimes falters and stutters on snapdragon x elite

Hi all

Recently I purchased a Surface Pro 11 Copilot  Snapdragon X Elite 

Photoshop works alright. 

However when I use most pencil brushes from Kyle from Adobe sometimes the lines suddenly falters. Resulting in dots instead of a straight line . 

I used the same Kyle brushes before, the same surface slim pen 2 and the same photoshop before on my old tablet: the Surface Pro 8 Intel i5 and the brushes worked perfect.

The surface pro 8 became to slow in ram memory, therefore i bought the surface pro 11 snapdragon.

I already used a quick fix. Cleared all settings of the brush. It helped a little but it stays buggy with sometimes faltering of the pencil. 

Can you guys help me out with this one?

And what would you recommend me

Keep the Snapdragon or buy back an older Intel version?

Thanks in advance
