Alienware

[RomanM89]

Hello, I have graphic problems with resizing/blurring in some apps like Tobii Experience or Visual studio installer. This problem happens on my Alienware Area R2 with GPU  GTX 2080 and screen 1080x720 300 MHz. I tried to fix this problem by reinstalling graphic drivers, updating all drivers and bios. I also tried to fix that problem as Windows rescaling text problem https://support.microsoft.com/en-us/topic/windows-scaling-issues-for-high-dpi-devices-508483cd-7c59-... , but nothing fixes my problem.

Do you have any advice or fixes? i attach screenshots

Hello Roman

Tobii looked the same on my m17 R2.

That mght be the same problem I struggled with after having done the October update of AWCC. Tobii and other software applications using WPF (Windows Presentation Foundation) seem to be affected negatively by AWCC's sound module (C:\ProgramData\A-Volute\DellInc.AlienwareSoundCenter).

But there is an exclude list: C:\ProgramData\A-Volute\DellInc.AlienwareSoundCenter\Modules\ScheduledModules\Configurator\BlackApps.dat

After having put "Tobii.EyeTracking.Portal.WPF.exe" (and some other affected SW applications) in that list, everything looks as it should again. BlackApps.dat is just a textfile and contains already 398 exclusions by default (goes from firefox.exe, chrome.exe to MyDell.exe and MyAlienware.exe).

You might try that - this is how: https://www.dell.com/community/Alienware/m17-R2-WPF-apps-distorted-disappearing-window-contents/m-p/...

Although this topic has been marked as resolved, I'm a WPF developer and see more and more user reports about this blurring UI. So I really hope the DELL Alienware Sound Center developer pushes a new update for the driver to fix this issue covering the Alien devices all over the world.

The NahimicOSD.dll is the critical file that breaks the WPF UI, renaming it helps. I've posted the issue and temporary solution early this month:
