Photoshop CC2017 brush stroke disappear and colorwheel stuck on screen

Since a few weeks, Photoshop CC2017 is "lagging" behind in a weird way.

• The color wheel stays stuck on the screen until I draw a brush stroke.
  
• When drawing a brush stroke, a whole chunk will disappear visually until I draw a second brush stroke.
  

This happens regardless of which brush I am using.
My laptop is rather powerful and hard disks are far from being full (so I don't believe it can come from scratch disks)

Thank you for your help

Edit : Thank you for your answers, just updated to 2019, nice update indeed but it doesn't help with my problem =/ exactly the same still...
here is an exemple of my problem

Fresh Paint - Multiple Brush Strokes??

Hi. Is there any way to lay down multiple brush strokes at the same time while using Fresh Paint? For example... when using the standard Microsoft Paint program if you drag all 5 fingers across your touch screen 5 separate strokes are laid down- 1 for
every finger. Is this possible with Fresh Paint?? If anyone knows of another program that does allow for this action, please let me know.. Thanks

 

Photoshop brush stroke moving canvas after windows 10 update

Hello all, whenever I try to make a brush stroke in Photoshop CC 2018, it moves my canvas as though I'm using the hand tool rather than actually putting down a brush stroke.

I have tried google to find the solution, and most of the forum says this problem is started after getting the windows update (KB4089848 ).

Any solution ?
