Windows flickers in 'Single Window' mode

Add Another Person to the List

I'm having the same screen problem as anyone else. For me, it started when I upgraded to 10.5.3. I was rock solid before that.

MacBook Pro 15"
OS X 10.5.3
Parallels Build 5600
XP SP2 Guest OS (transported from a work laptop)

The only slight difference for me is that I run two virtual machines (not at the same time), i.e. one for work stuff and one for home stuff. My "home" XP virtual machine is working flawlessly as usual with no screen problems. It's only my "work" virtual computer that has the flickering issue. Very odd.

BTW, thanks to the poster who mentioned this issue goes away in full screen mode. Luckily, I run multiple monitors and so for me, I can get around this by giving Parallels its own screen.
 
The connection between 10.5.3 and the flickering is well established now. It is assumed that Parallels is in communication with Apple regarding this unfortunate development. It would be reassuring and welcomed to have a progress report from a Parallels monitor on this forum regarding the steps being taken to resolve the matter. Thank you.

Indeed. This thread and others have provided (at considerable inconvenience and time)
information on the details on what triggered this problem and what's been tried to fix it.
Without success.

Not a big ask for one of the Parallels team to have the courtesy to respond back acknowledging the issue and provide some feedback. But then again maybe it is.

Hi,

Add me to the list too. I had Parallels Desktop 3.0 Build 5600 running fine on my iMac 24", OSX 10.5.2. But the screen flickering started after updating the OS to 10.5.3.

Add me to the list as well. I have had the problem so far on 2 MacBook Pros both running 10.4.10 or later. One was a newly imaged Mac and a clean install of XP. This was with the latest build of Parallels and XP
 
Possibly unrelated, but since this problem developed my Boot Camp partition has started having serious XP hard drive problems, after running XP trouble-free for about a year. It looks like MS Office is hosed, and goodness knows what else. The Mac partition is fine.

Going to full screen seems to reduce the flicker problem but not completely eliminate it. I had slightly better luck with the "iconize Parallels" suggestion, but then the system (disk) really went to hell.
 
Just another flicker issue

Hi All,

Flicker Problem on Windows VM seems to be a really well reported issue based on what I see in this string of discussions. Problem is there is nothing offered in the way of a fix or even a time line for a remedy.

I am uninstalling Parallels and trying VMWare Fusion.

I need a stable solution and the feedback seems to be generally good with Fusion.

Mac Powerbook Pro
2 GHz Intel Duo Core
2GB RAM
OS X 10.5.3
Parallels 3 5600
 
Same issue,

MBP,
2.33Ghz Core2 duo
2GB RAM

Happens on Windows XP. Have not tried vista, but RHEL4 GNOME/etc no issues.

Glad to know it's not just me.

It must be something with OS X 10.5.3.
 
mfejes: I certainly sympathize with your decision to go to VMWare, but to be candid, these companies leapfrog one another in terms of problems and also in terms of technology. Just read the respective forums over several months and you'll see what i mean. It's like deciding to change lanes in a traffic jam; might work for awhile, than maybe not so much. I have so little interest in riding herd over the "Borg's" software that I am going to stick with the Parallels team and work around the present issue by using coherence or full screen mode until a fix is posted rather than trying to translate the VM or reinstalling. I have better (Mac) things to do.

Same problem...Snapz Pro helps...

First, it's comforting to know others are working on this. Mine flickered a lot and started more or less randomly. I noted that someone here tried to record it using Snapz Pro and said he could not capture it. I tried the same. Turns out that it seems to halt the behavior. So, my workaround is to have Snapz Pro in the background and when it starts flickering I invoke it, make a short recording, delete it...and the flickering stops, at least for a while.

Waiting for something more permanent...

Flickering on MacBook Pro 15" running 5560 and OS 10.5.3

I have the flickering problem too with my MacBook Pro 15" running Parallels 5600 and OS X 10.5.3 since installing the OS update last week. I use my MacBook heavily during the day to run my business and the necessary WinXP software (ACT! CRM, Outlook and IE).

I have the same software installed on my MacPro 8-core running Parallels 5600 and OS X 10.5.3, but I have not noticed any flickering on this set up. However, I only use the Parallels/WinXP Pro occasionally on this machine.

At least Parallels tech support has acknowledged the problem and that a fix will be forthcoming. Soon, I hope.

Thank you, John (from all of us)! This is very welcome news. Now that the engineers know what caused the problem, are there any warnings or suggestions for us in the meantime? For example, I'm wondering if my data corruption episode was coincidence or potentially related to the bug.
