Question / Help Window Capture only capturing part of window

[Squiiddish]

I recently got SubAlert set up for my stream, but OBS is unable to capture it properly for some reason. With window capture, it only captures about 2/3 of the SubAlert window.

However, if I open the properties window to try to do something like, say, set up a sub-region, OBS is registering the entire window (bonus you can see all my window cap settings, I just tried turning Compatibility mode on to see if it wouild help. I have tried both Inner Window and Entire Window)

I've tried restarting both programs in different orders, redoing the SubAlert capture from scratch entirely, and about everything else I can think of. How can I make OBS capture the entire greenscreen area?

Why are you using window capture for this? Use the CLR browser plugin

This isn't Night's SubAlert app, I don't know if this one is compatible with CLR. I don't see anywhere to get a URL from SubAlert to plug into CLR.

Is there a reason OBS can't capture this window properly?
