Some applications rely on Internet Explorer to provide HTML rendering capabilities. Wine implements the same functionality based on a custom version of Mozilla’s Gecko rendering engine (the same engine used in Firefox). In Debian Jessie, you have a package called libwine-gecko-2.24 (the version is part of the name), which provides this rendering engine for Wine. However, different versions of Wine require different versions of wine-gecko. The package provided in Debian Jessie matches the Wine version provided by wine-development from the main Jessie repository (1.7.29). Unfortunately, wine-development from jessie-backports is version 1.9.8 and requires wine-gecko version 2.44, which is not provided by any Debian repository. This will lead to errors like
Could not load wine-gecko. HTML rendering will be disabled.
and blank spaces where HTML content would be rendered in many applications.
The solution is to manually install the required version of wine-gecko. We start by downloading the MSI binaries provided by Wine:
$ wget https://dl.winehq.org/wine/wine-gecko/2.44/wine_gecko-2.44-x86.msi
$ wget https://dl.winehq.org/wine/wine-gecko/2.44/wine_gecko-2.44-x86_64.msi
Now install the required one, based on whether you are using a 32-bit or 64-bit Wine environment:
wine-development msiexec /i wine_gecko-2.44-x86.msi
(Be sure to set the correct $WINEPREFIX if needed.)
