I am testing at work with a totally dpkged environment with chef doing the maintenance. I turned off the chef stuff last week so that it wouldn’t re-overwrite my 26.3 deb file. I’ll turn chef on, downgrade to 26.2, turn off chef, test, install 26.3, test and report back. That should keep the environment consistent between the two emacs versions.  I’ll also send along a list of all the debs and the yums. Yeah we configure our vms as redhat 7.3 or 4 or 5 ( I’ll look tomorrow) and then all the stuff we build is in dpkg (because we have to support Solaris and aix too); I would prefer not to identify my employer so please don’t ask. Or comment. :-)

The change I mentioned there was for Bug#24500 and Stefan's complaint
is in Bug#24803.  I doubt these are related to your switch from Emacs
26.2 to 26.3.  Did you, when you performed that switch, upgrade other
parts of your environment too?  And if so, can you try once more with
Emacs 26.2?
