Xbox Series X Weird Graphical Glitches

Hi,

I bought an Xbox Series X about a month ago, and recently I noticed some weird graphical glitches, I'm not exactly sure if all of them are inflicted from the same problem, but the glitches are:

1) White pixels or blocks poping in the screen - This is the most frequent one.

2) Black blocks poping in the screen.

3) Weird artifacts poping in the screen.

4) Wrong textures popping in some objects (and the right textures are switched immediately afterwards).

The video here demonstrates these problems on a few different games:

All of these problems only occur sometimes (while the first problem is the most frequent) and only for a fraction of a second every time, I didn't notice these problems when I first bought the xbox (though it's possible that I just didn't notice it). All
four problems happen with an LG OLED65CX when I used 120hz and VRR with the hdmi cable the xbox series came with, but at least the first problem on Gears 5 and at least on Watch Dogs Legion (it's probable that also some of the other problems will happen on
more games than those two, but I'm not sure yet), also happens when:

1) I disabled VRR

2) Set 60hz through xbox settings without VRR.

3) Set 60hz with VRR.

4) Limited the resolution to1080p

5) Disabled HDR.

6) Connected my xbox to a 1080p samsung tv.

7) Replaced the hdmi cable with my one (it was not an HDMI 2.1 cable)

It happened with all color depths or spaces (generally I set it to 10-bit standard). I also tried to power cycle my xbox and to do a factory reset, but the problem persists.

My Xbox should be well ventilated, it is standing in an open space and the objects/walls from the sides of it are about 15-30cm away.

I've googled a bit before posting here and it seems there are some posts regarding problems similar to this, but I'm not exactly sure if it's the same problem or a bit different one, also it seems people solved it by disabling 60hz, disable VRR or use a
different HDMI cable, which does not solve it in my case.

Is anyone familiar with this sort of problem and might know a possible solution or alternatively does someone know if this is a hardware problem and I should send my console for repair?
