Screen is glitching

I tried to build today in the sims 4 and the screen kept on glitching, I thought at first that it was because of mods and I removed them even though I only use mcc command centre and nothing else. The screen kept glitching and I recorded the screen so that I could complain to ea. Once I managed to get in contact with them they told me that they couldn't open the video file.  They are Misalignment glitches in which the objects jump around the screen. This happened every few seconds in which it was so frequent that I couldn't even see the objects anymore. I first chatted with one person and then with another and I tried every single thing: connectivity, I cleared the cache twice because that's what they told me, I deleted and reinstalled the app, I updated my computer, I restarted my computer, I did everything and the issue wasn't fixed. Because I could see that on here I can't post the video of the screen glitching I took screenshots of it and it doesn't give the full representation but just imagine this sort of thing happening every 2 seconds. At the end of the chat with customer support they just told me that it's not the game's fault that this is happening. I would like to know then, where is the fault. They always say to delete mods and that mods are at fault or that something is wrong with the computer we are using but this is not true at all. The same issues are occurring even when everything is changed. It has been extremely disappointing and frustrating to play the game lately. The last time I had an issue was a few days ago in which my pets were not working, I went into cas to make a dog and I saw that all of the dogs and cats were the same size, same color, same shape. No matter which breed I entered, they still remained the same as well and nothing could be done. I contacted customer support then as well and the problem was not fixed either. they just told me to randomize the pets until I get the one that I wanted. They are extremely unprofessional and disgusting with this behaviour. Not even trying to fix the issues just upload more and more dlcs... 

As they are screenshots grabbed from the video you'll need to look closely to the images to notice the mistakes. Just pay attention to the windows and stairs see how they are all glitched out. The stairs from downstairs appearing on the upper floor even though I have no stairs on the upper floor, windows moving and glitching, the stairs disappearing from the place, the park from next to the building appearing in my living room.. all sorts of glitches
