Ok, in fact this is a duplicate of bug #357326
MLT needs a video profile that is a multiple of 8. So adjusting your profile
width to 544 will make it work. I will add some safeguard / info to the profile
creation dialog

What happens if you resize the clip/project monitor (in a way that makes the
video smaller/bigger)?

If doing that solves it, it might be related to

Actually, my Kdenlive crashed, and when I restarted it, this issue seems to
have gone away. I think it might have been some leftover from updating today.

Ah, I was too quick to close this. It seems that the clip sometimes plays
distorted in both the clip and project monitors and sometimes it doesn't.
Weirdly enough though, what seems to make the difference, is the project
settings (yes, even for playback in the clip monitor).

If I create a new project with the standard HD 720P 30fps profile, I can import
and play this clip fine.

If I create a new project with the following settings, and import the clip it
plays corrupted:
Size: 540x960 (the resolution of the clip)
Frame rate:30/1
Pixel aspect ratio: 1/1
DIsplay aspect ratio: 540/960
Colorspace:ITU-R 709
Progressive

Not sure if it's related, but running in GDB I see a lot of errors like this
one:
QXcbConnection: XCB error: 8 (BadMatch), sequence: 1994, resource id: 10486065,
major code: 130 (Unknown), minor code: 3
