Weird glitches beetwen UE windows

Hi.
I was working fine in UE5.1 but now I’m having a really anoying problem, sudenly the different windows inside UE flicker beetwen them, main viewport (current map), play preview, materials, project settings, even tooltips… It happens in different projects I have been working but not in new ones.
in this links you can see what’s happening:

Windows (11) and Drivers up to date, nothing more than power cable connected
I’ve completly reinstall UE, look for problems with gpu drivers, run UE with another windows user but nothing seems work

please help, I don’t know what else to do.

If it’s an Nvidia GPU, downgrade your drivers to the ‘studio’, and reset all the options in the Nvidia control panel to default.

Thank you.
I’ve always had studio drivers and I’ve reinstall full clean up to date drivers.

Is it working? Did you reset the 3D options in the control panel?

Reset by global and by program.
No working yet. :anguished:

Hmm, not sure.

You could always play in viewport, and the just press F11 for full screen. ( F11 again to go back ).
