If anyone else encounters this phenomenon, then I have a card for it
It took a while. Before I managed to get to the right size, on which paint does not dry up vertical lines
So far this is over 14,500,000 Pixels
This is 3930x3709
3919x3527
3700x3600
3400x2700
I tested on def setting and on the old seventeenth version (pud-style on which you can see this effect more quickly)
For example, a slightly smaller 3919x3626 card is not good
