Padding around maximized window in split monitor

I've split a Portrait mode monitor (#3) vertically: 2560x1440 into two 1280x1440 halves. Whenever I maximize a window in either split there is a bit of "whitespace" on the left side of the window. It's not the desktop itself as I can't right-click or otherwise interact with it and it happens to every program I've tried (except Skype for Business?!?). Any ideas?

This is a workaround we had to put in for a Windows bug on systems that have multi-DPI setups. Windows in Windows 10 have invisible borders, so if we try to put them right at the edge of the screen, Windows gives us the scaling setting for the left monitor, since the application window's 0x0 point is on that monitor. When we then try to resize the window to fit the split, it gets the wrong size/location values because the scaling factor is incorrect :(

You can resolve this if you change the scaling level for all monitors to be the same value, but understandably that's not always workable for everyone :)

Please let us know if you have any further questions at all.

Thanks!

Should be an option to disable this workarround on single monitor setups with multiple divisions, as ther is no chance to have different DPI on each "monitor". I'm talking about "enlarge the windows through all monitors (toggle)".

I'm attaching my config. I divided my only monitor (ultrawide) on three regions. If I choose "enlarge the windows through all monitors (toggle)" a padding is left under and on the sides of the window (screenshot attached). If I choose "maximize window (ignore divisions)" it fills the monitor without paddings, but it takes a couple of seconds to do so.

Ah ok, thanks for the clarification! That's actually related to something else. Looks like we're not compensating for the invisible window borders with the span window function. I've added that to our list to investigate and fix up if possible.

Regarding the slow "Maximize (ignore splits)" function, that's on our list to fix up as well. In the meantime, if you enable the "Use Alternate Method To Move Windows (for testing ONLY)" option in the DisplayFusion Settings > Advanced Settings window, that should workaround the issue.

Thanks!

Thank you. I enabled "Use Alternate Method To Move Windows (for testing ONLY)" but the lag is still there.

I notice when I move windows arround via key presses, they move without filling those paddings, then a split second later, they fill it.

So to clarify, with that option enabled, "Maximize Window (ignore monitor splits)" is still slow to do the full maximize as well?

Both actions still have the same two seconds lag.

Edit: but only from maximized window. From normal window both are instant.

Thanks! I was able to reproduce this here as well. We'll be sure to follow-up when we've gotten it all fixed up.

Thanks!
