Hello,
My new 6600 started glitching about 3 weeks ago after 3 months of good functioning. It could be happened after a Windows or Amd update but I don't remember for sure. The fact is that glitches can disappear under certain conditions. If I shut down the pc and then turn it on again but with the monitor already on and in standby there are good chances that there will be no problems. Also after multiple restart I can find the round where everything is ok. But if I look carefully I can still find some bugs sometimes, like very small glitches in letters etc. It's like, when the PC turns on, is decided if it is gonna be glitching or not, very rarely happens that if is ok at start later it will start doing glitches, e.g. after opening an app.
Also, the only time when with the above method I tried to gaming, I got a lot of stuttering.
Things I have noticed or tried:
No bugs with Windows basic display driver;
New and Old Amd driver, Pro or Adrenalin, full or minimal install, don't fix the problem;
Display Driver Uninstaller or Amd cleanup utility don't fix it;
Refresh rate or resolution don't change anything;
Windows 11 fresh install doesn't fix the bugs;
Changed HDMI cable or port in Tv, it didn't work;
Integrated CPU graphic works ok;
FurMark stress test seemed ok (temperature was good, fans were spinning);
I noticed some wild GPU clock speed spikes in Amd Adrenalin but I read it could be the software causing it.
I try to attach some video for reference.

I have already contacted the reseller because I am still in warranty but they don't answered my mails. The Gpu was gifted to me by my mom who bought from a website very popular here (Italy) but with a lot of bad reviews for awful customer service. So I have little hope for a substitution.
Thanks for your help, it is appreciated.
Greetings.
