Macbook Air M1 Graphic problems

Hello Apple Community

I have my Macbook Air almost for a year now, never had serious problems. Lately, I noticed some weired graphical bugs in the games.

Never noticed something in a daily usage, only in the games.

I play Warthunder and Kerbal Space Program for example. Warthunder was bugging since I play it, but i was not thinking, it could be a Mac Problem. After the loading screen, game just freeze, sometimes I had to shut it down with power button, sometimes I killed the task.

Now it's on a another level, see my screenshot. Ingame it's a big flickering pixel on every smoke, dust or fire. Now, textures are going wild. I tried every settings ingame.

How can I reset the driver or what the M1 have? I always have the latest update on everything.

I don't know how to google this, I tried but nothing found.

*On the last two screenshots it doesn't seen so bad, but it's flickering the whole time in all colors.
