If you get a chance to try that out, let me know how it goes.

Thanks! ]]> RE: mirroring bug https://www.displayfusion.com/Discussions/View/mirroring-bug/?ID=6940e6df-eb60-45a4-961d-f7eb35dc3642#17 Thu, 08 Oct 2020 16:35:22 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/mirroring-bug/?ID=6940e6df-eb60-45a4-961d-f7eb35dc3642#17 DisplayFusion I am running sli on two 2080 Tis with slightly older drivers (a few months old at most maybe). I could try testing without SLI at some point when I get a chance. I'd say it's more accurate to say that it working correctly is intermittent. That one time when I was trying to reproduce the issue is the ONLY time I've ever seen it not have the issue in a long time. ]]> RE: mirroring bug https://www.displayfusion.com/Discussions/View/mirroring-bug/?ID=6940e6df-eb60-45a4-961d-f7eb35dc3642#16 Thu, 08 Oct 2020 15:35:05 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/mirroring-bug/?ID=6940e6df-eb60-45a4-961d-f7eb35dc3642#16 DisplayFusion I'm stumped! I still can't reproduce this here. Left is the original window, right is the mirror window.

My only guess is it's maybe graphics card driver related. If you enable this option in the Advanced Settings, does that make any difference?

Sounds like it's intermittent then? I'll do some more testing here and hopefully we'll get this sorted out :) ]]> RE: mirroring bug https://www.displayfusion.com/Discussions/View/mirroring-bug/?ID=6940e6df-eb60-45a4-961d-f7eb35dc3642#14 Wed, 30 Sep 2020 08:38:56 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/mirroring-bug/?ID=6940e6df-eb60-45a4-961d-f7eb35dc3642#14 DisplayFusion I'm at a loss right now. I was just about to post saying that I couldn't reproduce the issue no matter what I did, but then I accidentally rebooted my computer and it started happening again.

Idk if it matters but my mirror windows are borderless. Also my taskbars auto hide and there is no red border around the mirrored window. Also I have splits configured on the surround display with bezel correction enabled. ]]> RE: mirroring bug https://www.displayfusion.com/Discussions/View/mirroring-bug/?ID=6940e6df-eb60-45a4-961d-f7eb35dc3642#10 Mon, 14 Sep 2020 20:34:40 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/mirroring-bug/?ID=6940e6df-eb60-45a4-961d-f7eb35dc3642#10 DisplayFusion

You have it maximized to the smaller display? Which one is the mirror? Maximize both to 2560x1440 ]]> RE: mirroring bug https://www.displayfusion.com/Discussions/View/mirroring-bug/?ID=6940e6df-eb60-45a4-961d-f7eb35dc3642#9 Mon, 14 Sep 2020 20:16:26 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/mirroring-bug/?ID=6940e6df-eb60-45a4-961d-f7eb35dc3642#9 DisplayFusion Strange!

As I said, the mirror window just needs to be enlarged to a sufficient size. Maximizing both the source and mirror instantly causes this issue. ]]> RE: mirroring bug https://www.displayfusion.com/Discussions/View/mirroring-bug/?ID=6940e6df-eb60-45a4-961d-f7eb35dc3642#7 Mon, 14 Sep 2020 20:01:32 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/mirroring-bug/?ID=6940e6df-eb60-45a4-961d-f7eb35dc3642#7 DisplayFusion I can't seem to get this to happen here.

Thanks! ]]> mirroring bug https://www.displayfusion.com/Discussions/View/mirroring-bug/?ID=6940e6df-eb60-45a4-961d-f7eb35dc3642 Fri, 14 Aug 2020 11:54:32 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/mirroring-bug/?ID=6940e6df-eb60-45a4-961d-f7eb35dc3642 DisplayFusion on beta 3, recently updated windows, but not sure if that triggered this or not.

when mirroring a chrome window, attempting to make the mirror wider than (I think?) 2048px (provided the mirror is also of sufficient height), causes the mirror to render the chrome window incorrectly. The main area of the window is compressed and the most part of where the window should occupy becomes grey.

edit: not just chrome. ]]>
