closes #1766

Please cherry-pick to 1.3.x branch as it's a regression :P

Sorry my mistake

Added backport label, now @morevnaproject can easily filter PR that needs backporting.

Merged. Thank you!

@morevnaproject please don't forget to filter by Backport lable for open and closed PR XD

[rodolforg]

Whoops. This problem doesn't happen in 1.3.x :P

[morevnaproject]

I think this problem might appear in 1.4.x branch as soon as I backport latest Text Layer changes there. So, let's leave the "Backport" label on this PR. ^__^

as soon as I backport latest Text Layer changes there

I do not remember which PR I was about to backport 😭

[rodolforg]

@morevnaproject maybe you could check via git log synfig-core/src/modules/lyr_freetype/ the last commits of a branch and another :P
Would it be about font caching or combobox for font family support?

Thank you! I have looked through them and I couldn't find the issue I looking for ^__^". I remember we had a discussion there about backporting, but I couldn't find those messages now. Well, anyway I remember there were problems with backporting (some conflicts), which was prevented me from cherry-picking that PR into 1.4.x...
