During fullscreen games the taskbar on my secondary monitor flickers. I've tried using compatibility settings, I've tried with both, the option for reloading during full screen checked and unchecked with no success.

This seems to have resolved the issue.
Many thanks for the quick solve

Hi, for me it still flickers if I don't use "Ignore Full Screen Windows", with it i get a Taskbar on the game screen, which i don't want. Game runs with compatibility settings.

Is there a fix for this?

I have three monitors, Left one has windows Taskbar.
Middle one is for games with DisplayFusion taskbar, but its set to disappear while games run.
Right one has again DisplayFusion taskbar which flickers, but only sometimes, and sometimes only the Start button.
After activating "Allow taskbar reloading while full screen applications are running" it got less frequent.

I could only reproduce the flickering of the Start button, which happens constantly.while playing World of Tanks. Doesn't happen with any other game.
Flickering of the taskbar doesn't seem to happen anymore.
The taskbar still appears sometimes on the game screen for a few seconds (not in this log), it is apparently connected to Windows notifications.
If I get any of these issues again I will send another log, but that could take some time.

Sure, there you go.

No, still the same.

Hi! I also have the issue where the DisplayFusion taskbar is appearing and disappearing occasionally when having anything in fullscreen (games, videos, etc). I have a license key for Steam, how do I access the beta version there?

Again, I'm not sure how to update to the Beta when I have the license on Steam?
The link does not work, so not sure if you wanted me to do it here? https://www.displayfusion.com/Download/Beta

Hi again, the issue has bee completely fixed for me.
Thank you very much for the great support!

@xFayeFaye I don't know if its the same for the Steam version, but in the "normal" version go to Settings -> Options under "Update Check" enable "Check for new Beta ...".

I am on the beta and still having this issue. I have a full screen RDP taking over two monitors and the third monitor has a Display Fusion taskbar that flickers.

That's Correct. I've attached a screenshot of my display settings if that helps. I'm also on Beta 3

I'm sure you're still working on it but in case the latest beta had some undocumented fixes. I just installed beta 6 and it's still an issue.

Just had this same issue for the first time, so it's still an open bug!

Using the Steam 10.1.1 version of DisplayFusion.

While playing Dragon Age Origins in *windowed* mode, occasionally the taskbar on my second monitor flickers to display my desktop background behind it for half a second. The "Ignore Fullscreen Windows" fixes this flicker for *some* cases, like pressing `shift`, but just clicking the screen in general triggers it.

If it matters, I'm using Borderless Gaming release 9.5.6 to maximize the game window on my primary monitor. I'm running the game as administrator, with core affinity 1 and in Windows XP (SP3) compatibility mode.

I've never seen this flickering before on any other app or game on this PC, with or without Borderless Gaming, Flawless Widescreen, or any other overlay or window modifiying app.

Unfortunately, I haven't been able to reproduce the flickering. It randomly(?) stopped happening a few days after I made my intial post here so I'm going to assume at this point it was a fluke. If it happens again I'll make sure to record and a attach a debug log, apologies for the falseish alarm!

Hey Keith,

I stumbled upon this issue myself. I ran into another post of yours to address an issue I have with RDP sessions, wherein the DF taskbar overlays the RDP, hiding the session's taskbar and such. I was able to address this by creating a compatibility rule that forces it to treat the mstsc.exe instances as a fullscreen application.

However, as a result of this, it is causing my taskbars to flicker, namely my monitor 1 with monitor 2 sometimes doing it. Strangely, it only happens when the RDP window is not minimized to the taskbar.

I attached the debug log, per your instructions. I recreated it a few times with the most recent being around 11:09 AM Central, today, 10/10/23.

Weird. But, yeah, it's only on one monitor. These are also launched via RemoteApp if that has any impact.

I'm having an issue with my DF taskbars flickering when using VMware Horizon to connect to a remote VM. I tried the "Ignore Full Screen Windows" option which stopped the flickering but caused the DF taskbar to appear on top of my Horizon VM. Is there a fix for this?

Sorry to hijack this topic but it's been happening for me as well, the flickering. Ever since I've tried to fix the issue of DF taskbar being shown when there's a fullscreen like Youtube video on Chrome. I tried to Disable the option for "Show taskbar in front of full screen applications when they lose focus" and it did fix that, but the flickering has started ever since and no matter what I change I can't seem to fix it, it does go away for a while after reboot but it comes back.

Monitor setup (2 monitors, right monitor is primary, left monitor is secondary)
Monitor with DF taskbar (left monitor, secondary)
Monitor with Windows taskbar (right monitor, primary)

Taskbar that flickers is the DF taskbar on the left monitor. Please help....

Same after updating to 11.0 Beta

Sorry but I used BC Uninstaller and removed all registry files associated with DF 11 and installed a stable 10.1.2 from Steam (because I have a Steam key) and now the problem no longer occurs. Will wait a while before upgrading to 11 again

Seems like I can't help you either, because this fix helped me at first


And now when I turned it off and enabled logging, the taskbar isn't flickering. But I'll keep an eye on it.

Just started happening again while firefox is running with youtube, log attached

it was on primary monitor and flicker always occurs on secondary
and the video wasn't fullscreen

edit: duh, on primary the taskbar is native so it won't flicker
