Dev channel update to 86.0.587.0 is live
I've been following the Dev channel of Edge since it first became available for Windows. When version 84 came to Dev, DPI issues arose, and have since shipped to stable. I've used twitter back in May (bad source for reports sorry), the feedback tool built into the browser a week or 2 ago, and now I implore you here on Tech Community. Every version of Edge since 84 up to at least this version of 86 have broken mixed DPI issues. The attached video explains it visually (no audio).
Monitor setup: 2x 1920x1200 at 100% scaling, one of which is my main display, and 1x 4k laptop monitor at 250% scaling.
The first half of the attached video is when Edge is on my leftmost, main 1920x1200 display, and shows right clicking tabs to use the context menu for duplicating, or re-opening closed tabs renders fine, but clicking on the ... menu spawns the menu on the laptop screen, clipping out of the viewport. This problem gets worse as you attempt to navigate sub menus in the ... menu. Any website with a native <select> element will do the same thing (so it's not just shell elements), making those websites very hard to use.
The second half of the attached video is when Edge is on my secondary 1920x1200 display, and shows that the ... menu renders correctly, but right clicking tabs to use the context menu for duplicating, or re-opening closed tabs spawns on the laptop screen, clipping out of the viewport.
Using Windows 10's application compatibility settings to override application scaling to use System (enhanced) will making both the 1920x1200 monitors work fine in all cases, only the browser becomes blurry on the laptop screen. This has been my workaround for now, but I'd love to see Edge resume normal DPI functionality. Maybe I'm in the minority of people experiencing this.
Any word on this DPI issue?

AdamDotNet It would help to know what your monitor topology is in Windows: which edges of which monitor are next to which other ones? We've had issues before where Edge gets really messed up with its hit testing near mixed-DPI boundaries, so this looks like another one.
josh_bodner - Happy to add details here. Attached is a screenshot of my display arrangement. Monitors 3 and 2 are right next to each other and level, with the laptop screen lower and to the right, with only a small portion of the edge against monitor 2. Let me know if you would like more details!
AdamDotNet that helps! If you want to play around with it more, it would be interesting to know which edges of which screens are susceptible to this, since it sounds like it's not just the boundary between screens of different DPIs (which is quite small as far as Windows is concerned).
