B4J Question (Solved) Graphical issue. Blank and frozen screens

A few weeks ago I bought a new PC with Windows 11. Everything was perfect, no problems.
A few days or a week ago, I started having problems with B4J.

All applications freeze after two or three minutes of running, with the screens frozen, and if you open a new window, it appears blank. All new screens appear blank.
Interacting seems to speed up, but it always ends the same, after a few minutes.
The application continues to work perfectly, but without screens.
The problem occurs on 3 machines with Windows 11 that I have been able to test, and on one it does not.
On Windows 10 it always works without any problem on any machine.

I suspected some recent Windows 11 update, but apparently there is no difference between the 3 PCs on which it does not work and the one that does work.
Everything done with B4J fails. In release, in debug, with Packager, with Java 8, 11, 14. And even applications made two or three years ago.
I have also tried with Windows 11 Sandbox, and in addition to the same thing happening, not even the wysiwyg of the visual designer works anymore. It also appears always blank.

No error of any kind appears at any time.

Has anyone else encountered this problem?
Any help would be appreciated

Tested with Java 19. Exactly the same behavior.
Sometimes instantly, sometimes after a while, but always ends with frozen windows. The funny thing is that the buttons work, they do what they're supposed to do and the application works, but with frozen windows and if you open a new window it appears blank.
I've done hundreds of tests. I don't know where to go next.

Have you tried running the program in Windows 11 Safe mode? May be a graphics driver-related issue. Also see if anything changes when you change screen resolutions and/or color depth. This will confirm a graphics/video hardware or driver issue.

Finally it was a graphics card driver problem.
For each window that was opened, the resources consumed increased by 20%, and with 5 or 6 windows, it hangs.

My adapter is an INTEL UHD Graphics 770 on an ASUS PRIME B760-PLUS board
The driver used was 32.0.101.5972

I tried with 101.6048 and 101.6078 and it does exactly the same thing.

Using an old driver (September 2022) version 31.0.101.3678 everything works perfectly, as it had always worked with windows 10, and there is no way to make it crash for many windows you open.
Resources go up, but reasonably and without ever running out.

In other words, it WORKS
Thanks for the contributions

It is clear that the current drivers have a problem. I hope that in future versions this will be fixed.
