I am going to screenshot this post as an example. Fullscreen applications randomly hide behind the taskbar making certain website unusable because of inputs at the bottom of the screen.

It is happening with the Discord App, Opera GX, Steam, Epic Games Launcher, Jagex Launcher etc.

Windows 11. DF Pro (Steam) v9.9.

I have taskbar position manually set to Bottom.

Show taskbar in front of full screen is disabled in settings.

It randomly happens 1/4 times I start my computer without having to actually change setting and having to restart my pc just for a program to work as intended is becoming very cumbersome.

Pictures showing the issue attached with numerous programs including YouTube on Fullscreen.

Debug is attached.

I am NOT running Start11

Flicking that setting hasn't fixed the issue. Now the taskbar is hiding behind maximised applications like Discord and Chrome (I can't see it).

The only way to make the taskbar visible is to move all applications to the other monitor and only then does the bar become visible.

When I move the applications back to the other monitor they taskbar overlays the bottom of the window before disappearing a few moments later.

Restarting explorer through Task Manager does not solve the issue.

I am having this same issue with all applications. Any ideas?
Running Windows 11 pro (21H2, 10.0.22000.0), Display Fusion Pro 9.9

I am now running Beta 10.0 (Beta 16) and it is fixed! Thank you.

On restart, the issue seems to have fixed itself but it seems to intermittently return.

While the issue is temporarily resolved, I'm getting this weird intermittent flicker on the taskbar where it seems to momentarily flash/disappear and return. Once every second for like a couple of milliseconds like it isn't keeping up with the refresh rate of the monitor or something.

I've noticed I can reproduce the issue if I turn the monitors off and turn them on again as well. Once this happens, the taskbar no longer registers and disappears completely. When it shows up, it is hiding the bottom portion of maximised windows. I have shared two debug reports before and after reproducing the bug to see if there are any inconsistencies.

There's another issue which seems to have popped up around the time of installing DF, but I'm not entirely sure if it's related or not. I'll run some troubleshoots. The issue is in the first 10 seconds of turning monitors on (whether its at startup or when windows has fully logged in after a period of time) I get this crazy flicker of both monitors on and off for about 10-15 seconds. Once this time passes the monitors are acting like normal.

I've read this could be a driver issue which I updated around the same time as installation so I'll wait for nVidia to update their drivers before linking the two or ruling out DF. For reference I'm running a nVidia 3070.

I have similar issues,
currently using Win 11 pro 22H2.

Issue 1: Full screen chrome extends below taskbar with taskbar in front of chrome
Issue 2: Every time I open display fusion, it requires steam to open and stuff.

Hi there I have the same problem with 2 out of 4 of my monitors - particularly an issue when some applications have buttons appearing at the bottom that become invisible, and for applications with tabs at the bottom. I checked Advanced Settings and no default settings have been changed. Nor could I find the "show taskbar in front of full screen applications" option mentioned above. I've attached my debug file FYI

Hi Owen. sure please find attached. You will see when I start taskbar is hidden and you can see the application tabs, when I change taskbar status to visible the application does not adjust and the tabs are hidden under the taskbar. This is the case for all applications. Thanks a lot

Hi Owen, it happens when autohide is disabled - I have only started to use autohide because I can't access the tabs on said applications! will let you know how I get on with the beta install

Hi I installed v10.8 but it doesn't seem to have changed anything, see video at this URL, once again with autohide disabled, the application is maximized and the tabs are set beneath the taskbar:

Sure here it is

I can confirm the same issue occurs for me. The only remedy is to restart- which is obviously not convenient.

I had it happen again and this time I told DisplayFusion to restart Windows Explorer. After restarting the Windows Explorer process, the windows are now displaying properly- so that is quick fix in the future... Open Task Manager, select Windows Explorer then Restart task.

Here you go...

Hi Owen, sorry for slow response, thanks this seems to have resolved the issue for me. When it fails I get a message advising there is a memory issue and to restart windows. After this has happened the problem is resolved.

Hi guys. What do I do when this situation happens but the windows reset box doesn't appear? is there an easy way to manually reset windows explorer? I tried John's solution but can't see Windows Explorer on Task Manager

I have found that my machine enters this state rather reliably after I go from an undocked state (laptop-only) to a docked state (laptop plus 4 screens). I do not shutdown or anything between these states, I plug and unplug while I am in the middle of things. I do it this way because I need to be mobile and I don't like losing the state of my apps. I am hoping this further information can help lead to a permanent fix.

Hi Keith, I can confirm the manual reset works, I managed to rerun explorer.exe by clicking on "Run new task" in Windows explorer.exe, but most times the auto reset is kicking in. Like John I am running 4 screens and often very low on memory so assume will happen less when I get a more powerful laptop. Thanks for your help

Echoing this -- going from undocked to docked (2 monitors in my case) is exactly when this happens for me. Displayfusion's function for half-screen left/right (which I use constantly) hides the bottom under the taskbar. Using Windows' Snap function dragging the window to the left or right does work (but obviously I like DisplayFusion's function including keyboards shortcuts infinitely better). Restarting explorer.exe did not work, but following Keith's instructions to end the explorer.exe process on the details tab and then start it as a new task, did work.

edit: My computer is not short on memory (16gb RAM for mostly office work).

Having this same issue on v10.1.2 Win 11, 32Gb of RAM. After finding this thread, restarting explorer seems to fix it.

Has there been any solution to this issue? I have had this for well over a year. It is intermittent and restarting explorer does reset the problem but thats a frustrating work around for a $50 piece of software I literally only purchased in order to be able to change between 3 screens. like thats the only thing i use it for. to switch between my two pc monitors and my TV. because windows cant handle 3 screens apparently. And basically ever since ive bought it ive had this issue and theres been no fix i can find. please update.
