Just in time for the general release of fedora 25 next week (2016-11-22, see the official Schedule) the Pantheon session works again, after the following changes landed recently:
- Support for
libmutter-3.22has been merged into the
galatrunk branch and is present in the stable and nightly repositories now.
wingpanelhas also received support for linking against
libmutter-3.22in bzr trunk (which already is in the nightly repo). The stable build now uses a workaround in packaging until a new stable release containing the upstream fix is available.
- The other problem, which resulted in
plankbeing scaled wrongly on HiDPI screens has been fixed in upstream
gtk+. A snapshot of its stable branch containing the fix is in the stable and nightly repos now - until an upstream release containing the fixes is made available.
