Description Tom Sullivan 2020-08-31 16:51:09 UTC 
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.

Confirmed, it works with gen, but not with gtk3.

this typically happens when the tooltip area is set to a point instead of a rectangle
