I just retried it in 2433 and the following skins had the issue:
- Material Design
- Material Design (Dark)
- Metro M
- Monkey groove
- Black Monkey
- Code Monkey
- Golden Monkey
- Purple Haze
- Red Devil
(I guess that's all of them)

Which Build (Help > About) and Skin are you using?

Yep same issue, staying with MM4 till this is fixed, latest build of MM5, Win 7 with scaling at 125% cant see most of the menus properly at all

Here you go. The video contains a recording of both of my screens.
The right side with 125% scaling, the left side with 100%. If I open the properties window on the left monitor, the borders appear to be the same weight on all sides, as do the borders of the main window.
After moving the window to the right screen, the left and top border are notably thicker than the left and bottom one.

Edit:
I just noticed that, due to scaling and compression, window borders are a little hard to see, so here are two screenshots of the properties window:
100%:

125%:

It definitely is an issue related to scaling, so you are correct there.

I can't replicate the issue on build 2291, could you upload a recording of it?

Not sure if it's the same issue, a variant of it or a completely new one - today I noticed that the issue (using 2291) doesn't seem to be related to moving windows around, but rather to the scaling factor at which a window is created.

If I open Mediamonkey on a screen with 1920x1080 and 100% scaling factor, all windows and dialogs render correctly with all borders displayed and nothing cut off.

If I move the main mediamonkey window to a second screen with resolution of 2560*1440 with 125% scaling, all newly created dialogs have a few pixels cut off at the bottom and right side of the window.

This also applies to the main window, but the new scaling factor is not applied immediately when moving between windows, so to see an effect the window needs to be maximised and restored first.

Hi Lowlander,
I also noticed that even the top row menus were truncated when I tried to do File --> Exit for example, but all menus across the top have the same issue.

Can't reproduce the problem with Properties after MediaMonkey restart after DPI change, but menus and Properties do appear out of place with 150%.

Hi Team,
I cannot find the reference to the tracker number to verify if these are intended to be included in this release, but the truncated menus and the windowed positioning issue still persists in b2264.

1. I am running a 3840x2160 monitor at 150% scaling. Every time I open MM5, the windows position if partially off screen and to the lower right side. I resize and reposition, close, and it reverts back to the lower right and larger size.

2. If I right click on a file, the menu shows up fine the first time. Then I click on properties and the expanded menu is truncated on the right side. If I close out and right click on the file again, then the initial menu is also truncated on the right.

I'd like to add that I'm experiencing the same issue in 2262 as well, but without having to move the application between screens. The issue just randomly occurs right after starting mediamonkey, about once out of 15 times I start it. Restarting mediamonkey or reloading the skin fixes the issue for a while.

The primary screen that I have the application running on a resolution of 2560*1440 with a scaling factor of 125%, while the second screen uses 1920*1080 with 100%.

Confirming it's somehow caused by moving MM between monitors with different scales. Will check and fix that.

Just to confirm that I have made sure that my PC has totally up-to-date in terms of Windows 10 and drivers for the graphics card etc. Unfortunately, the problem remains the same in MM5 (but not in MM4).

It seems that in the case of dual screens, moving the application between the screens causes some sort of issue that causes sub-menus to be truncated to the bottom and right hand side.

From reading this thread, it also seems that the problem is evident for various scaling options.

Spoke to soon! After initially installing MM5 2262 and selecting some menus everything worked fine. Upon closing and reopening 2262 the MM5 window did not remember size and position and menu's were once again truncated as previously stated in thread. This happened ONLY after a left click on album art to highlight all songs and then right click on highlighted songs to open properties. Initially the prescribed left click, right click action opened the menus without truncation. However, upon selecting the properties window it opened truncated, and any subsequent menus selected were truncated. Still using Windows 10 with 125% scaling. Pictures attached to demonstrate behavior.

This is NOT solved for me with b2262. I am using 4k monitor at 150% scaling. Screen is exactly as shown initially by Ian.

It was useful to know that the issue has been fixed for some.

I think there is a little more too this!

When I open the application initially in the main screen - everything is OK. However, as soon as I move the application to the second screen the sub-menus are truncated. Moving the application back to the main screen, the sub-menus are truncated.

I am aware that there may be a pending Windows 10 issue with the display so I will check after updating Windows and checking drivers are all up-to-date etc.
