QUESTION
When I attempt to preview my Markdown (e.g. the included uberwriter_markdown.md
tutorial), the preview appears momentarily, but vanishes after an instant, leaving me with a blank screen until I revert to the raw view. I assume that this is a local configuration issue (I've had problems with GTK Flatpaks before, for reasons unknown, and simply switched to apt
repo versions instead). Would anyone know of possible workarounds that might solve this issue?
WHAT I DID
I installed all of the packages mentioned as prerequisites in README.md (installing webkit2gtk-driver
at version 2.22.6-0ubuntu0.18.04.01
via apt
) and then installed the Flatpak like so:
$ flatpak install flathub de.wolfvollprecht.UberWriter
Looking for matches…
Required runtime for de.wolfvollprecht.UberWriter/x86_64/stable (runtime/org.gnome.Platform/x86_64/3.30) found in remote flathub
Do you want to install it? [Y/n]: y
