Hi, from some weeks I'm having a problema with Windows in coherence mode. A white border around the windows appears and in some windows all the background changes to white. I'm attached some screenshots. My system is a Mac Mini M4 Pro with 64GB RAM Sequoia 15.6 and the installed version of Windows is Windows 11 24H2 26100.4770 Regards
Hello @JoseL43 , @DavidB189 , Please note that this is being investigated by our development team. Once there is an update we will let you know. Thank you!
Same issue since a few weeks on my MacBookPro M4 w 48GB. It seems shadows and blurring background isn't running correctly (i guess it is since Parallels Desktop v26)
Same issue on MacPro Intel running latest Windows 11 24H2 26100.6725 Version 20.4.1 (55996) In addition, windows under coherence keep going out of focus (being pushed behind other apps / windows on macOS) when selected ie. start menu, file manager etc.
@Adarsh Jeetun Hi there! It's been over two months already -- is there any update or fix for this issue? It's been quite a long time.
Hi, this is happening since summer in 24H2. an update fixed the issue on my side, 2025-08 Cumulative Update Preview for .NET Framework 3.5 and 4.8.1 for Windows 11, version 25H2 for arm64 (KB5064402). but it came back with 25H2 yesterday's latest Prod patches, so the issue is back 2025-10 Cumulative Update for Windows 11, version 25H2 for arm64-based Systems (KB5066835) (26200.6899) 2025-10 Cumulative Update for .NET Framework 3.5 and 4.8.1 for Windows 11, version 25H2 for arm64 (KB5066128) Everything was fine until this moment 2025-09 Cumulative Update Preview for Windows 11, version 25H2 for arm64-based Systems (KB5065789) (26200.6725) so uninstalling both latest October patches fix the issue
