Current ScummVM git snapshot
English CD version of the game
I noticed that some subtitle boxes are not drawn/erased correctly. The text sticks up over the decorations that are supposed to be in the upper corners, and when the box is erased it leaves what was above those decorations behind. I'm going to attach a screenshot to show what I mean.

Apparently this is a bug in the original game as well. I couldn't find any way of enabling both speech and subtitles, but manually editing RESOURCE.CFG allowed me to see subtitles in DOSBox. I'm attaching a screenshot of what that looked like.

I forgot to mention that I checked a "let's play" on YouTube of the floppy version, and in that version the speech is split over two speech boxes. I assume they were merged for technical reasons when the speech was added.
Fixed in a73e3f44add407f28f1b790d11a9317200a2cb39.
The large text boxes are removed correctly now, but are still drawn oddly (i.e. they are drawn outside their respective text window rects, thus the window decorations are off), but that can't be helped - more invasive changes would be required, for a feature that wasn't present originally in that version. Thus, I consider this bug to be resolved. Closing
