Hello,
On the modeline, on the "Major mode" keyword, for example
"Fundamental", mouse button 1 and 3 cause a context menu to show
overlapping the modeline.
On a two screen display of uneven size, on the smaller of those two
screens, when the X11 frame for emacs is maximised fullscreen after
using the F11 key for toggle-frame-fullscreen, that context menu
grows offscreen and unreadable.
Similary, on the smaller screen, an X11 frame for emacs with the
bottom of the frame put near to the bottom of the smaller screen,
that context menu grows offscreen and unreadable.
# steps to reproduce
## maximised X11 frame for emacs on smaller of two screens
1. start emacs by "emacs -Q"
2. move the emacs X11 frame to the smaller screen of a two screen
GNU/Linux LXDE
3. press F11 for toggle-frame-fullscreen
4. press button mouse-1 or mouse-3 on the "Major mode" keyword for
context menu
## not maximised X11 frame for emacs on smaller of two screens
1. start emacs by "emacs -Q"
2. move the emacs X11 frame to the smaller screen of a two screen
GNU/Linux LXDE
3. move the bottom of emacs X11 frame to bottom of the screen
4. press button mouse-1 or mouse-3 on the "Major mode" keyword for
context menu
# observed behavior
The context menu grows offscreen and unreadable.
# expected behavior
The context menu "floats" as it grows, showing all the rows on the
context menu.

What toolkit is your Emacs built with? Is it GTK+? And if so, what
version of GTK+ is it?
In the future, please use report-emacs-bug to report this kind of bug.
It avoids having to ask these questions.
Thanks.

The x-toolkit is "lucid". Here is the clip from the config.log in
the build directory.

I don't have emacs configured for email and worry the mechanism might
misfire. Sorry about that. I just discovered the config.log file is
1Mb long and decided not to include that in the attachment.
These are all the libraries associated with the emacs binary. I want
a skeleton thin build for my basic need but don't really know what to
exclude. Hope this helps.

There's no need to be afraid of that. report-emacs-bug first prepares
a buffer with all the data, and then waits for you to invoke a command
to send that as email (after adding the specifics of the problem). So
you can just copy the information it prepares to your MUA and discard
the buffer afterwards.

I'm afraid using the contents of config.log to determine Emacs
configuration usually causes a great deal of trouble to both of us: you
really ought to use `report-emacs-bug'.

You don't have to send it from Emacs, you can copy the report into your
favorite mailer and send it to bug-gnu-emacs@gnu.org.

That rarely helpes as well, especially in this case, because the Lucid
toolkit is builtin to Emacs and not dynamically linked.

The bug is gone. The full context menu displays within bounds on all
screens of the display. Attached is the bug-gnu-emacs report on host
characteristics building off master.
The ELC+ELN stage of the build doesn't make use of multicores. If it
could detect there are 4 cores and do something like 'make -j4' that
would be an improvement on time to build completion.

Great, I'm closing this bug report.

You mean, during building Emacs? If you say "make -j4", there will be
4 ELC+ELN compilations running in parallel. So I'm not sure I
understand the complaint.

Yes, during the Emacs build. I haven't experimented to see if "make
-j4" will allow 4 parallel lanes of ELC+ELN compilations. That would
be nice. I'm saying "make bootstrap" detects there are multiple
cores and suggests or defaults to using them all in parallel whee
possible.

Then please do use "make -jN bootstrap", where N is the number of
execution units you have on that system. That's how you request
parallel Emacs builds.

The way we natively-compile Lisp files during a build was
intentionally made serial, so that the Make command could control how
much parallelism is in use. Because otherwise, we could easily
overwhelm the CPU, because the inherent built-in parallelism of the
async native-compilation doesn't care about the system load, so
invoking "make -j8" would give you 8 compilation jobs, each one of
which could use 4 cores.

Thanks, I will do that the next time.

Thank you for taking the time to explain this. I was seeing one of
the CPU bars 100% and the three other ones idle.
