            Bug ID: 136336
           Summary: LO Writer does not display footnote text on mouse
                    hover for GTK 3
           Product: LibreOffice
           Version: 6.4.6.2 release
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Writer
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: Tom at SullivanInUSA.com

Description:
Upgraded to 6.4.6.2. When I hover the mouse over a footnote number in the main
text, there is no popup showing me the text of the footnote. This used to work.
I do have tools/options/LibreOffice/General/Extended Tooltips checked. Running
Debian buster, XFCE 4.12
 tested it on a different computer also running Debian Buster. The problem
appears on both XFCE and LXDE. The other computer uses Debian's video drivers,
the first, Nvidia.
Thanks to forum user Opaque for this finding: From my tests: it is a problem
when using the gtk3 VCL (See in Help -> About LibreOffice) The problem happens
on all combinations of LibreOffice versions and desktop managers (Tested: MATE,
LXDE, LXQt, Plasma and Xfce). Even "Plasma"-desktop doesn't select VCL:kde5 but
a mixed VCL:gtk3_kde5 which also does show the problem. I did not succeed
running LibreOffice in VCL:kde5 mode, which normally could be forced using
SAL_USE_VCLPLUGIN=kde5 libreoffice (forcing GTK3 on my other system also shows
the problem) - Hence my conclusion is: This is a general problem of the GTK3
support of LibreOffice (if not of the GTK toolkit issue at all).

Steps to Reproduce:
1. Type some text and include a footnote in it.
2. Put some text in the footnote.
3. Hover your mousepointer over the footnote marker in the main text.

Actual Results:
Nothing happens.

Expected Results:
You should see the text of the footnote pop up a little after you stop moving
the mouse.


Reproducible: Always


User Profile Reset: No


OpenGL enabled: Yes

Additional Info:
Problem appears on multiple machines by different users, so resetting user
profile not applicable.
