parallels full screen display breaks up after swipe from mac screen
- Thread starter AxelH3
- Start date
Yeah, same issue as everyone else is reporting. I was on Sierra last week and upgraded to High Sierra over the weekend and now get it about half the time when I four-finger swipe or Command-Tab from my Mac to Windows in full-screen mode. I found that if I try to take a screen capture of it just shows up as solid grey, in case that gives you any clues as to where the bug is. Per previous poster it would be good to see Parallels acknowledge this issue, as it's clearly pretty widespread.
- Hardware: MacBook Pro (Retina, 13-inch, Late 2013), 16GB RAM, 2.4GHz i5, 256GB SSD, internal display
- MacOS: High Sierra 10.13
- Windows: Windows 10, Version 1703, OS build 15063.608
- Parallels VM configuration: 7GB RAM, 2 CPUs, 512MB graphics memory, Resolution: "Best for retina display"
I found this article in the Knowledge base: http://kb.parallels.com/en/123840
in which the video artefacts problem is referenced (5th item down). On first reading it, I thought that it was referencing problems relating to Parallels 12 (and earlier) and hence the advice to upgrade to Parallels 13. Having read it again, I think they are saying these problems exist even with Parallels 13, so that for this particular issue, as with some others, no workaround is presently available.

I found out a temporary fix/little trick.
Easiest way for Windows 10/8/7: http://www.thewindowsclub.com/display-seconds-in-taskbar-clock-windows
Explanation:
Ever since macOS High Sierra update, I have also been having problems with the "video artefacts" when switching desktop spaces. I use the "swipe to switch desktop spaces" all the time, and this is really annoying. However, when information "updates" on the virtual OS monitor, it seems to refresh the information on screen and makes the virtual OS monitor back to normal. Examples of what I am talking about:
Note: I have only tested this in Windows 10 (with the registry modification only available for Windows 10 v1607+), however the link above have steps to enable it with Windows 10/8/7 also using a third-party program. I have not tested to see if this is a problem with other guest OS's but I assume they are.
Similar steps are possibly available for Linux guest OS's, and I know there is an option for macOS for enabling seconds.
All you need is any program that changes information on screen at least once a second (and visible), so a program with a changing taskbar icon will work too, as long as the icon is not hidden.
Feel free to reply to my post if anybody has any questions on how to do this. Hope this little trick helps others!

- Blinking cursor in Windows 10
- Refreshing of icon in Windows Taskbar
- Clicking command button while Windows virtual machine is active, opens start menu
- When the time on the taskbar changes

Hi @JiyoungC,
Please, make a report about the problem and send it to Parallels.
Go to Menu->Help->Send Technical Data
If it possible, also write here number of report
I had version 13 installed when I originally posted on this thread (as I wrote at the time). I was getting artifacts on swiping across from Mac to Windows even after the two updates to version 13 received since. Even with the fix I referred to above, I still get screen break-up on first swiping across, but the faster refresh rate prevents it happening thereafter.
UPDATE: I've just installed the newly released MacOS 10.13.2 Update on both my MacBook Pro and MacBook Air (each of which is running Parallels version 13 with a Windows 10 VM) and the artefacting issue now seems to have been rectified. I've disabled the registry solution I referenced above since it no longer appears to be necessary.
