Text not displaying within Windows 11 VM after updating to Parallels Desktop 19

Any ideas on how to fix this issue? I'd like to avoid reinstalling my vm's back running Parallels 18?
I've tried adjusting Parallels 19's display / hardware settings, running Windows cmd prompt system scans, re-installing Windows and running all system updates... Any ideas on possible troubleshooting methods to resolve? Image 1-5-24 at 12.33 AM.jpg ?

Hello!
In order to proceed with further investigation, kindly provide us with the below information:
1. Reproduce the issue.
2. Collect a technical report (right-click Parallels icon in Dock > Help > Send technical data > check "Attach screenshots..." > press Send Report) and send the report's 9-digit ID in a reply.
Thank you!
 
Does the problem also appear when your virtual machine is running under Retina Display resolution? That changes the system font used, so it may be able to coax Windows into displaying its text!

Select View > Retina Resolution > Best for Retina display and see whether the text appears then. If it doesn't... you may have to re-install Windows (in another virtual machine?) to see if that rectifies the problem.

I spent hours reinstalling windows and parallels I finally fixed it by adding the flag "video.metal=0" to the boot order advanced settings flags. After that windows is working great and all menus are perfect!

Thanks very much for this advice it now works for me as well running W11 on par 17
 
I am pretty new to this sort of thing, so maybe in retarded, but how do I get the settings to let me input a flag in the boot order? when I try, the box to enter the flag text in flashed briefly and then goes dull (Not allowing me to input text) and I don't know how to do it. If I shut down the virtual machine, the issue remains the same, I still cannot input text...

You legend. This worked for me as well!!
I had installed Opencore legacy patcher and managed to get OS 15.1 Sequoia to work otherwise perfectly on my 2014 iMac. One of the things it does is patch the Metal drivers, so I guess this was causing a problem with Parallels. Turning off the Metal video has fixed everything.
Thanks again!
 
GlynH-
I have the same set up. Mid 2014 running with OpenCore Patcher/OS 15.2 Sequoia. Can you guide as to where I may find or how can I turn off metal video feature? Also, does it affect anything on the Mac when you using OS and not Parallels. Thanks in advance.

Worked for me too. To help anyone else you close windows altogether in parallels and then close parallels 2 steps then open only parallels and go to parallels icon at top right of your computer screen and chose the setting or preferences line or whatever it is as I'm away from my computer right now. Then in the menu that come up go to hardware and scroll to bottom I. The boot flag up section. Click advanced and a boot flag blank box pops up then put the phrase video.metal=0. No parentheses just the plain text. Close out the screens and close parallels and then reopen and the select your vr machine for either windows 10 or 11. It does matter which one it should work for both. I'm running an iMac with an intel i7 chip. Hope this helps anyone else out there. Took me 3 days to find and figure this out.
 
Also a very quick work around is to go to device manager and disable the parallels driver. Afterwards your text does show up and you can use all the functions of Windows 11. I've an older Mac and it is unsupported with open core program with sequoia. There was a recent update and after updating my Mac with open core everything was working on the non parallels video card. Even if you don't see another card, just disable the one you see there by right clicking and choose disable and system will refresh/ restart to default driver. I believe it was when I updated parallels software that it defaults back to the parallels driver so after updating I had no text again and repeated the process mentioned above for video driver.

Of course the video.metal=0 statement placed in the boot as mentioned in earlier threads has also helped me. Hope this helps anyone else. FWIW. With the default card it runs windows well. Not sure what parallels is doing about this. Just trying to share my journey with this issue and it may help someone else. I'd prefer to have the best driver to run it, but will take the fact that I am functioning on the basic driver now

Try adjusting display scaling in Parallels settings (Scaled/HiDPI), and ensure your graphics drivers are updated in the VM. Reinstall Parallels Tools too.
