Region map - "blue city glitch"

[El Presidente]

Hello dear community,
I have a glitch that kinda ruins the entire region map and makes it impossible to select cities that are behind giant blue rectangles that appear at played cities and makes it impossible to select the ones behind it.

Here are examples of what I experience:

I have tried to change the resolution to lower than 1080x1920, switch to hardware mode for once (which made the game crash on launch), applying the 4GB patch and I also set the game in compatibility mode (Windows XP - Service Pack 3).

Sadly none of these seemed to have done anything and it doesn't look like a lot of people have this problem.
Has anyone experienced those blue rectangles in the region and graphical glitches while moving the camera in the city before and found a fix?

These is my system if it helps:
Intel Core i7-10700k
NVIDIA RTX 3070
16Gb of RAM
The game is installed on a HDD but I also have a SSD.

I've never experienced this so I won't be of much help, but do you have any mods installed? Maybe try removing them if you do? Idk.

Nope, I just have vanilla.

Good news everyone!
I found a fix!

I followed this video after making my game completely die on me after switiching to software mode for the yolos.
I already installed the SC4 Fix file but
1. I put it in the wrong plug in folder (needs to be located in the SimCity 4 DOCUMENTS folder)
2. I put "-intro:off -CPUcount:1 -CustomResolution:enabled -r1920x1080x32 -w" (Without quotations) in the starting option but I had something similar in it beforehand.
3. Something that I didn't do before was to turn off HiDPI .

The results are the removal of the blue squares, the graphical you get while moving the camera and increased performance!

I'm leaving this here for everyone who has the same problem in the hopes that someone in the future will not need to spend a good chunk of time to have this game running properly! :)
