Drumline Extention installation causing bloated text

Hey there! First time posting, so bare with me here, but this issue only occurs when I try to install the Drumline Extention for Musescore.

Stats:
OS: Windows 10 (10.0)
Arch.: x86_64
MuseScore version (64-bit): 3.0.3.5734, revision: 5a0be2a
Screen size: 1366x768 (Pictures are less than 1366x768 due to them only being limited to the musescore window for privacy reasons. Window size has not been changed between image 1 and 2.)

Steps to recreate issue:
When booted as normal with Drumline Extention uninstalled (as by default), everything is laid out fine and no issues occur. Text is how it should be (see image 1, "normal.png").

Help > Resource Manager, click "Install" on MuseScore Drumline extention line. Wait for installation to complete as normal. Afterwards, the text in the workstation becomes big and bloated (see image 2, "blown up.png"), even sometimes too big for its confined space (see "MuseScore Drumline" text under Extentions in image 2).

Problem persists after fully closing and reopening Musescore. Only until I uninstall the Drumline Extention will the program just suddenly crash, to which I can restart the program and text is back to normal.

The project files themselves (new, reopened, or otherwise) are not pertinent to, nor do they seem to change, the issue.

If anybody can shed some light on this issue, that would be wonderful! Thanks for your time.
