Subject: Blank tooltips in Cairo
Date: Wed, 19 Jun 2019 16:14:57 -0400

Hi all,

In cairo builds, when x-gtk-use-system-tooltips is set to nil, running (x-show-tip "xyz") produce a blank tooltip on my machine (the tooltip has the right dimensions, but is blank).

To reproduce, you can run the following:

    emacs -Q --eval '(progn (setq x-gtk-use-system-tooltips nil) (x-show-tip "xyz"))'

Cheers,
Clément.

This one happens in non-Cairo builds too.

Probably a separate issue.  It seems like a regression by a proposed
fix of Bug#23925 (not yet applied).  Please try below instead.

Oops, wrong bug number.  Also, I should have added
control <at> debbugs.gnu.org to Bcc:, not to Cc:.  Please remove it when
replying to the previous post.

Perfect.  With this patch tooltips work and the previous issue is still fixed as well.

Thanks a lot!

Thanks for testing.  Expecting further fixes for Bug#34819, I've
pushed a different fix to master as 2a229f495fe.  Closing the bug.
