See #255286.

Quite hard to investigate until #255286 is fixed.

See #263073.

The problem is that changes were made upstream in xlibs to improve support
for multiple layouts.  Some applications are confused and fail to handle
the current keymaps.
So there are 2 solutions:
  a. Fix xlibs.
  b. Fix those applications.
(b) is most of the time trivial and safe (ie. a working configuration
is not broken by applying this patch).  OTOH changes in xlibs are very
tricky and fragile, and AFAICT such changes have currently been
performed neither by upstreams (XFree86 or Xorg) nor by other distributions,
so I am afraid that Debian XFree86 maintainers are very reluctant to go
for (a).
