Application window grows each time it's run

[Fixitman333]

I'm using four monitors in the following configuration:

Top> 1600x1200 (4:3) @100% scaling
Left> 1920x1200 (8:5) @100% scaling
Middle> 3840x2160 (16:9) @150% scaling
Right> 1920x1200 (8:5) @100% scaling

I thought EDOMH was "forgetting" it's window position due to this setup. Now I've realized it's actually increasing it's size down and right on every launch. It does this consistently on all except my middle monitor. It retains it's correct size on every launch on that one.

I took screenshots of three successive launches on the right monitor, and opened them in my graphics editor. Upon zooming in for exact coordinates, I found the following pixel locations:

1> Left= 5788, Top= 1259, Right= 7651, Bottom= 2365
2> Left= 5788, Top= 1259, Right= 7657, Bottom= 2382
3> Left= 5788, Top= 1259, Right= 7663, Bottom= 2399

It's increasing it's width by 6 pixels to the right, and it's height by 17 pixels downward. The window eventually ends up with it's right and bottom edges off the monitor because of this.

I'm guessing this is somehow related to either the differences in scaling and/or the aspect ratios. I'd appreciate a fix if possible, but this is not a critical issue. I've been seeing this since version 2.21 (now on 2.89), so I'm used to it.

If it was solely related to scaling, I would expect larger changes. These changes seem to be more related to borders and titlebar in conjunction with scaling. It as probably something in whatever size gets reported and how the app initializes. It can be very dependent on the OS and whatever window theming and customizations you have, so I would at least need additional information to be able to even look into this.

You can also disable scaling temporarily to see if the issue persists.

another though is that it could be caused if the screens are not properly aligned.

I'm running Windows 10 21H2 with an EVGA 3080 Ti. I have it set to as close to a Windows 7 theme as possible using Open Shell.
Aligning the monitors perfectly is impossible due to the dissimilar resolutions. The monitor layout is in extended (not clone) mode like this:

I tried changing the scaling on the center monitor to 100%, and that resolved the issue. I have to switch it back though, because I can't read anything on the main screen that way. I changed it back to 150%, and launched EDOMH again. It then launched completely off of the right side of my right monitor. I was able to get it back on-screen by changing my scaling again, launching EDOMH, and moving it to the center monitor. I was then able to set scaling back to 150%, and move it back to the right monitor. The issue returned as expected.

This definitely appears to be related to scaling. I also run Firefox on my top monitor, EDDiscovery on my left monitor, and Elite Observatory on my right monitor. None of them have this issue.
