The issue with Chrome is actually different than the one with ISLC. ISLC is actually changing its window when we snap it for some reason. Chrome is jumpy because we had to disable hooks for it (they are blocking hooks completely soon) and we tried to code a workaround for Window Snapping for Chrome. Unfortunately it's not reliable and results in the behaviour you're seeing. We'll just be disabling Window Snapping for Chrome completely in the next beta as there's no other option without hooks ]]> https://www.displayfusion.com/Discussions/View/issue-with-window-snapping/?ID=8a63d9c8-0d5e-4a54-a1c1-03ad3e1a71b3#11 Wed, 17 Oct 2018 19:40:02 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/issue-with-window-snapping/?ID=8a63d9c8-0d5e-4a54-a1c1-03ad3e1a71b3#11 DisplayFusion I wish my video capture in Snagit was functional because this is rather difficult to film with a phone while using the other hand to show the erratic snapping/movement issue, heh. ]]> https://www.displayfusion.com/Discussions/View/issue-with-window-snapping/?ID=8a63d9c8-0d5e-4a54-a1c1-03ad3e1a71b3#10 Wed, 17 Oct 2018 18:50:52 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/issue-with-window-snapping/?ID=8a63d9c8-0d5e-4a54-a1c1-03ad3e1a71b3#10 DisplayFusion Could you attach a video of Chrome doing it as well? ]]> https://www.displayfusion.com/Discussions/View/issue-with-window-snapping/?ID=8a63d9c8-0d5e-4a54-a1c1-03ad3e1a71b3#9 Mon, 15 Oct 2018 18:18:21 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/issue-with-window-snapping/?ID=8a63d9c8-0d5e-4a54-a1c1-03ad3e1a71b3#9 DisplayFusion Chrome:
Version 70.0.3538.54 (Official Build) beta (64-bit)

No custom theme but I do use a couple flags which may affect the window behavior:

I tried setting both of them to Default however it behaves the same after. It's not as severe as ISLC since the window size isn't affected, but when moving any Chrome windows next to other windows or monitor edges, it seems to jump away from the edge(s) rather than sticking to the edge(s); same as ISLC in the video minus the window size changes. ]]> https://www.displayfusion.com/Discussions/View/issue-with-window-snapping/?ID=8a63d9c8-0d5e-4a54-a1c1-03ad3e1a71b3#8 Mon, 15 Oct 2018 18:11:53 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/issue-with-window-snapping/?ID=8a63d9c8-0d5e-4a54-a1c1-03ad3e1a71b3#8 DisplayFusion I can repro this with ISLC but not with Chrome. What version of Chrome are you running, and are you using a custom theme or the default? ]]> https://www.displayfusion.com/Discussions/View/issue-with-window-snapping/?ID=8a63d9c8-0d5e-4a54-a1c1-03ad3e1a71b3#7 Fri, 12 Oct 2018 17:44:45 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/issue-with-window-snapping/?ID=8a63d9c8-0d5e-4a54-a1c1-03ad3e1a71b3#7 DisplayFusion Ok, I'll give this a more thorough test here next week and see what I can find out.

Thanks! ]]> https://www.displayfusion.com/Discussions/View/issue-with-window-snapping/?ID=8a63d9c8-0d5e-4a54-a1c1-03ad3e1a71b3#6 Fri, 12 Oct 2018 15:56:55 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/issue-with-window-snapping/?ID=8a63d9c8-0d5e-4a54-a1c1-03ad3e1a71b3#6 DisplayFusion No, when snapping is disabled in both Windows and DisplayFusion, the window just moves past the edge and there is no snapping or change in window/titlebar dimensions.

If I disable snapping in DisplayFusion only and re-enable it in Windows, it doesn't snap to the monitor edge (while mouse button is held) but it moves the window back automatically to the edge after releasing the mouse button. No change in window/titlebar dimensions during the process, so this seems to be limited to the snapping function being enabled in DisplayFusion. ]]> https://www.displayfusion.com/Discussions/View/issue-with-window-snapping/?ID=8a63d9c8-0d5e-4a54-a1c1-03ad3e1a71b3#5 Fri, 12 Oct 2018 15:49:18 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/issue-with-window-snapping/?ID=8a63d9c8-0d5e-4a54-a1c1-03ad3e1a71b3#5 DisplayFusion In theory it shouldn't, no. If you disable snapping and drag that program to the top of the monitor does the titlebar still change in dimensions a bit? It seems like it's squishing up a little bit when it hits the top of the monitor. ]]> https://www.displayfusion.com/Discussions/View/issue-with-window-snapping/?ID=8a63d9c8-0d5e-4a54-a1c1-03ad3e1a71b3#4 Thu, 11 Oct 2018 00:12:36 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/issue-with-window-snapping/?ID=8a63d9c8-0d5e-4a54-a1c1-03ad3e1a71b3#4 DisplayFusion I've also noticed that it doesn't affect all applications... here's some examples of affected and unaffected applications/windows:

Affected:

Chrome
ISLC

Unaffected:

Windows Explorer
VLC

Should window snapping behave differently for different types of windows/applications? Not sure where the root of the issue lies. ]]> https://www.displayfusion.com/Discussions/View/issue-with-window-snapping/?ID=8a63d9c8-0d5e-4a54-a1c1-03ad3e1a71b3#3 Wed, 10 Oct 2018 18:19:47 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/issue-with-window-snapping/?ID=8a63d9c8-0d5e-4a54-a1c1-03ad3e1a71b3#3 DisplayFusion 3 monitors, same scaling level (100%), different resolutions (4k, 1440p, 1080p).

I've been having an issue with window snapping and I don't know what's causing it. When moving a window and it snaps to another application's edge, or monitor edge, it jumps around and/or changes in size slightly. When releasing the mouse button, windows also frequently move away from the edge it was supposed to snap to.

I didn't use to have this issue and I don't recall making any changes recently that could've resulted in this behavior, both in Windows 10 or DisplayFusion. I'm on Windows 10 1803, 17134.285 - DisplayFusion 9.4 Beta 3 but downgrading to 9.3 made no difference. Snapping is disabled in Windows, enabled in DisplayFusion.

Attached is a short video showing the described behavior. SnagIt wouldn't let me record it so I had to use my phone instead. It's not limited to the application window shown, i.e. I get the same behavior with a Chrome window.

Any help would be appreciated. Please let me know if you need any additional information.

Thanks! ]]>
