Applications menu is too narrow

### What Happened?

Sometimes the applications menu is too narrow (I guess about half its normal width). Killing and restarting wingpanel sometimes helps, but not always. Logging out and back again helps, but again, not always.

(I have a screenshot, but I'm not sure how to attach it.)

### Steps to Reproduce

1. Login.
2. Click on the "Applications" menu.
3. The menu shows up, but sometimes it's narrower than normal.

### Expected Behavior

The menu size should be consistent.

### OS Version

7.x (Horus)

### Software Version

Latest release (I have run all updates)

### Log Output

_No response_

### Hardware Info

I have an ATI/NVIDIA laptop and I'm running the nvidia proprietary driver in on-demand mode. The relevant `lspci` output:
