It could be unlikely that this (libepoxy) would be updated now in
Bionic, but I thought I had better bring it to people's attention just
in case anyone was considering requesting or has to review an FFe for this.

Subject: libepoxy 1.5 breaks KWin on NVIDIA

this is just a short information that the latest libepoxy release (1.5)
causes KWin to crash on NVIDIA driver. See  for more information.
I suggest to not update this package until the issue is resolved. For
distributions who already rolled out the update (I am aware of at least
Arch) I suggest to consider going back to the previous version. If the
KDE team in your distribution is not responsible for libepoxy I kindly
ask to forward this mail to the relevant developers.
I cannot tell you yet whether the problem is in libepoxy, KWin or NVIDIA
