That doesn't make sense, according to the info you use Skia with gtk3, but that combination is blocked. Maybe you have explicitly forced Skia (there's an expert 'ForceSkia' setting)?
(In reply to Luboš Luňák from comment #1) Yes you are correct - I must had enabled that at some point, and forgot. (But shouldn't the isVCLSkiaEnabled check return false in that case *if* it doesn't work there, even if forced? I don't know if it does, just asking.)
Luboš Luňák committed a patch related to this issue. It has been pushed to "master": https://git.libreoffice.org/core/commit/a65cba8e5bafb183924c1a8ff34382c99f1381cc make disabling of Skia override forcing it (tdf#133399) It will be available in 7.0.0. The patch should be included in the daily builds available at https://dev-builds.libreoffice.org/daily/ in the next 24-48 hours. More information about daily builds can be found at: https://wiki.documentfoundation.org/Testing_Daily_Builds Affected users are encouraged to test the fix and report feedback.
