When I log in to my desktop workstation (Ubuntu-MATE 20.04.3; kernel 5.40-94-generic; MATE desktop environment; Caja file manager), the text for the desktop-icons has bad (too short) line-breaks, as seen in the attached screenshot-1 (at left, below).
It's especially galling that the split will occur in the middle of a word, as in:
downlo
ads
If I open any one of those icons shown in screenshot-1 and go to the "Edit" menu in Caja, then down to "Preferences," in Preferences under "Icon View Defaults," I have "Use compact layout" checked.
If I UN-CHECK and then RE-CHECK that box for "Use compact layout," the line-breaks instantly correct themselves from two lines into one line, as seen in the attached screenshot-2 (just below screenshot-1), where they look the way they should.
(If I leave the "Use compact layout" box UN-checked, the bad line-breaks remain in place.)
I've gone several times into Main Menu -> Appearance -> Fonts and made various adjustments to permanently correct this problem, to no avail.
I'm guessing there is a way to permanently fix this, but how?
