[Bug] Window doesn't maximise properly (on Windows 10)

[Slackluster]

Apologies if this is somehow an issue with the OS, but fiddling with any related settings and searching for similar issues, I came up with nothing.

When maximising the F-Chat Rising window by using the maximise icon in the top right (next to the close button) or by double-clicking the top of the window, part of the UI gets cut off:

Only when using the Windows + arrow keys to move the window to the side of the screen and then dragging the other end manually to the edge of the screen, does the window show all of its UI:

Occasionally on boot the window does maximise properly and keeps doing so for as long as it's open, but most of the time it does not and will not maximise properly. I've yet to figure out if there is something factoring in here, testing with a selection of any/no other windows open on my screens (I run a 3 monitor setup) did not seem to make any difference. I was able to determine that moving the taskbar to the side of the screen causes the UI to get cut off at the very bottom of the monitor in the same way, so the issue is not with the taskbar specifically.

I am running v1.27.3, but this issue has been present since at least v1.26.1.
