System Information
Operating system: Windows-10-10.0.19041-SP0 64 Bits
Graphics card: GeForce RTX 2070/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 461.72

Blender Version
Broken: version: 2.92.0, branch: master, commit date: 2021-02-24 16:25, hash: 02948a2cab
Worked: (newest version of Blender that worked as expected)

Short description of error
Entire computer freezes and do not respond in any way, when using Texture Paint mode.
After a manual shutdown, have to wait couple of minutes before the start buttond of the computer works.

This must be related graphic card overheating .
After the crash I downloaded MSI Afterburner to check graphic card temperatures while working.
You can leave it on top while painting in Blender texture paint's mode.
Observe that whenever you make a trace, temperature of the GPU ascends. If you can leave time between trace and trace, temperature will descend, and stability will happen.
But if you accumulate several strokes, every one of them you make increases GPU temperature. If you keep making them until you reach 70º, 80º, or 90º... computer will crash.

Also, put viewport in Material Preview mode. In solid mode also happens, but less.

Exact steps for others to reproduce the error

With the default "General" scene, go to the Texture Paint workspace
Create a Tiled (UDIM) texture image with resolution: 2048 x 2048
In the Side Bar -> Image -> UDIM Tiles add or create another two 2048px textures
Paint on all of them several times. Constantly. After some traces added, entire computer freezes.
Optional steps:
Check GPU temperature while painting.
Put viewport in Material Preview mode. (In solid mode also happens, but less).

After reading several reports in the internet that Latest windows 10 version, 2020 h2 causes freezing and pc crashes, I chose to downgrade to 1909 to know if this was the problem.
Problem persists. Though you have to be more constant.
In paint mode, paint on any map (I tried color map ) making several clicks. GPU temperature increases per every click done. When reaches 69-70º pc crashes.

I edited the description because the steps were a little vague.
But even redoing all of them, I can’t notice the GPU temperature rise, freezing or crash.
Are there any steps missing?

No. I will try to check this in other computers to see if is my computer's fault.
If I find this in more computers I will record video. If is just mine, I will say.

I have made the following findings:
The pc where I was working in which this problem happened first, is a 15 inch laptop. I had the laptop connected to a TV, to serve as display. It certainly happens.
I've tried it in another laptop. This one is a 17 inch.
If I repeat the steps and I'm only using the laptop's screen, everything works ok. Temperature remains low.
If I attach this other laptop to a TV via HDMI, to display image there, the problem appears. It certainly happens much more slowly. I've had to press button several times to reach 69º, but it was increasing with no limit.

It seems that you have to do this with a laptop, connected to a TV, so this provokes the GPU to overheat in some way.
It is much faster in my 15 inch laptop. Since the pc is smaller, it has less room to have ventilation.

I am recording a video and uploading soon.

So here I am providing a video in which the problem happens and a .blend

ProblemScene.7z

The character was a simple character mesh done in free version of Fuse (steam version) with default options and exported to blender as .obj, done in less than a minute. Character doesn't have too much geometry, but certainly is not the default cube. I don't know if this can be related, but maybe.

Note unit scale is metric 0.01. This makes character very big, because if we would be talking about the same mesh in scale 1, the same character's height would be 100 metres. (So I think that internally, to Blender, the character is very big, and you always have to set the viewport clip start and end, to not to have visualization problems)

This character size is good to export to games. I don't know if this is related to the problem. Maybe the character is way too big and this stress the GPU when painting? I don't know...
Tell me if you need anything else on my part.

Folks!
Just after my previous message Windows 10 auto intalled new upgrades. 2 to windows. 1 to Nvidia display.
Upgrades are these, for you to know.

Problems seems solved!
I have tried to see if does something, and now it is much much more stable.
I cannot reach easily more than 64º painting heavily. Not in less than a minute, as seen in video. And I have been painting for 3 minutes continuosly.
Temperature rises slower now, and even goes down even when making some paint traces.

I'm detecting that If I make a paint of a colour, over the same colour (paint in green over an area where the same color green already is), now the temperature doesn't go up. It's now like the GPU knows that it must not update that area, so is doing nothing, so no unnecesary heat. It is optimized.

Noise from fans also do not rises heavily as before.
Seems fixed to me now.

If you agree, you can close this.

Good to know, thanks for the report.

There are plans (from the #sculpt_paint_texture team) to improve performance in this area, so problems like this should be much less frequent.
