I'm not sure whether this is the same issue as in the bug report, but
for me there has been a problem ever since I use Lazarus on Linux with a
"non mainstream" keyboard layout, which is for several years now. It was
behaving the same with Ubuntu years ago and currently I use a pretty up
to date archlinux, so for me it didn't change because of external libraries.
Dvorak has been mentioned and I'm using Neo (called Neo2 in most linux
distros). For me it is configured as the default layout in X11, tty and
my Xfce settings and I usually don't change it.

The issue for me is that some keys (even some single keystrokes) don't
work at all, do something different, or modifier keys seem to be
ignored, e.g. I can't type the letter 'ä', but strangely 'ö' works.

I have never tried Lazarus via VNC. For me the issue occurs when running
Lazarus just normal on the local X server. But it is only the SynEdit
component, which is affected. Other menus like preferences or
objectinspector work just like they should. And almost all other
programs like gedit, gnome-terminal, firefox, etc. don't have problems
either.
