Discord scales incorrectly on secondary display

When Discord is moved to my second display, it seems to shrink by about 25% and will shrink again and again if I click anywhere within or outside that application while within that second display. The mouse pointer also seems to be offset when trying to interact with any elements within that application. Discord also no longer remembers its window position when minimized/closed to system tray.

My assumption is these new behaviors are tied to a Discord update but thought I’d post here just in case.

I believe this is known to happen when extending the desktop to monitors of different DPI.

If I recall correct - it has been a while since the issue was last mentioned - you can adjust the behaviour in System Settings → Display & Monitor

Change the setting regarding Legacy applications for the monitor in question.

I did try this to no avail unfortunately. The application window behavior is the same regardless of which option I use. Appreciate the suggestion nonetheless.
