<pre>Description:
In the formmula {expression_1} underbrace {expression_2} if expression_1 is
large enough, the UI disappears and it is not possible to recover it without
closing LO.
Steps to Reproduce:
0. download first attachment (test_formula.odf)
1. in a terminal, launch LO with the following command : SAL_USE_VCLPLUGIN=gtk3
libreoffice6.3 test_formula.odf
2. in the command panel, add one letter at the end of first expression
(ABCD...)
3.
Actual Results:
View panel and command panel disappear and it is not possible to recover the
hand on LO. The only thing to do is to close LO using Ctrl+Q or the main menu.
In the terminal, I get several blocs of the following error messages:
(soffice:18182): Gtk-WARNING **: 21:32:09.346: drawing failure for widget
'OOoFixed': error occurred in libfreetype
(soffice:18182): Gtk-WARNING **: 21:32:09.346: drawing failure for widget
'GtkEventBox': error occurred in libfreetype
(soffice:18182): Gtk-WARNING **: 21:32:09.346: drawing failure for widget
'GtkGrid': error occurred in libfreetype
(soffice:18182): Gtk-WARNING **: 21:32:09.347: drawing failure for widget
'GtkWindow': error occurred in libfreetype
No other messages than these ones.
Same behavior if the math formula is embedded in a text document. If I open a
text document (e.g. the second attachment) containing such a formula with LO
under GTK3, the formula is not visible. If I try to edit the formula the UI
disappears. All formulas that follow the wrong formula become invisible.
If I use the generic backend (SAL_USE_VCLPLUGIN=gen libreoffice6.3
test_formula.odf) the underbrace becomes invisible when I edit the formula but
the UI is not destroyed.
Expected Results:
Be able to view and edit a math formula like this one.
Reproducible: Always
User Profile Reset: Yes
Additional Info:
Even if the formula is not visible, PDF export works as expected.
I reproduce the problem in LO 6.0 (from Ubuntu), 6.1, 6.2, 6.3 and master (all
built at home under Ubuntu 18.04 x86-64).
My version of libfreetype is 2.8.1-2ubuntu2</pre>
