Hello Manu,
Thank you for your feedback.
As a solution, Please re-install the Parallels tools by following the steps:
1. Start your virtual machine
2. In the Mac Top menu, click on Actions > Reinstall Parallels Tools.
3. Open the application and check again.
You may refer to this Knowledge Base for further guidance: https://kb.parallels.com/112609

If the issue persists, change your virtual Machine view mode to different mode using steps below:
1. From the Mac Top menu, Click View > Retina Resolution > "Best for Retina", to change the screen resolution.
2. Click Sign out and login to your Virtual Machine again.
3. Open the Application and check.

If the above did not work, please try to configure the emulation mode before executing the application:
1. Launch your Windows 11 virtual machine.
2. Right- Click on the application > Select Properties
3. Select the "Compatibility" tab > Change emulation settings > Click on Default and change it to "Very strict execution" > Press ok > Apply
4. Click on the Parallels Desktop icon on top of the Mac menu bar > Select Control Center > Right-click on your Windows 11 virtual machine > Select Configure
5. Select the "Security" Tab > Tick "Isolate Windows from Mac" > You will be prompted to sign out to Windows > Sign in again > Launch the Application.
6. Verify if the issue is still present ?
