I recently purchased DisplayFusion and I'm running into some issues with screen splitting my 40" 4k monitor:

Taskbars -the taskbars don't seem to work perfectly across the different splits, of particular problem are the mini-notification icons...you can see these on all three screens (I have things setup to have one screen on the left and two on the right with a horizontal split) but you only seem to be able to interact with the icons on the primary screen

Maximizing Windows -when you maximize a window, the bottom of it stretches below the taskbar which is a real pain, they also don't always fill all the way on the sides

This is a great piece of software but it's been very discouraging to try and get things working correctly.

Can anybody provide any advice that will provide resolution?

Thanks in advance!

Thanks for the followup Keither. I've attached the log per your request.

Another issue that has been introduced after my last reboot is that the taskbars on the right side of the screen (which I believe are the additional taskbars vs. the primary driven directly by Windows) has made the text too large in the date/clock and as a result it is pushed off the screen. The primary taskbar is the right size however.

I've included a screenshot which shows this issue as well as the window size being covered by the taskbar as well.

If it helps, I'm running this on a Surface Book.

A reboot did fix the text size in the taskbar so that's good.

However, still experiencing issues with the taskbar overlapping full-size windows.

Any ideas there?

The tray icons issue seems to have been resolved when I upgraded to Beta 10 (pre-opening this thread) so that's good.

The lingering issue seems to be the taskbar overlapping windows. I tried changing the padding to 0 but it still occurs (screenshot attached).

The padding was only set for the right/left and this issue seems to be on the vertical axis so I'm guessing it's not related.

All applications have the same issue.

If you look at the screenshot there you can see Outlook below the taskbar which you rightfully identified but it also shows Spotify on the top side going too low as well.

Unfortunately that doesn't appear to have made a difference. The windows when maximized still dip halfway below the taskbar (and the lower window extends halfway into it).

It's as if the windows are calculating the 1920x1080 section and maximizing the windows into the full space of that instead of accounting for the space used by the taskbar.

I haven't really setup much in the way of custom settings. Even when I was adding padding between the layouts before it was just trying to fix this issue.

I'm using a Surface Book which is a common enough system and it's a pretty new build. I haven't done anything funky with my configuration either that would cause issues like this.

Settings attached as you requested. Hopefully you can find something...it's getting really annoying!

I rebooted after installing Beta 11 (I hadn't rebooted before) and things are partially better.

Now the top right split works as expected and it fills the screen properly.

However, the bottom right split now fills the entire area under the taskbar above it.

Previously both the top and right splits would evenly fill half of the taskbar.

Screenshot attached.

I've also attached debugging per your request. Testing was done at 3:43pm EST (though the log should only be for like 2 minutes so it should be pretty easy to find.

Let me know what else you need.

Unfortunately that doesn't appear to fix things either. The bottom right window isn't overlapped but the top right window is overlapped at the top.

Something else I'm not sure I noticed before is that the sizing left-to-right isn't quite right either (2nd screenshot attached).

It appears what the taskbars believe is the center of the screen isn't quite the same as what the windows believe is the center.

I've uninstalled for now as I was getting frustrated with it. It also seemed to be causing issues when waking from sleep.

Have you tested on a Surface Book? I have the model with the non-discrete GPU and I suspect maybe DF doesn't play friendly with onboard GPU in this system.
