hi stuart.
thanks extremely for confirming my bug!
i am not familiar with technical expressions, but
is the issue realy because of openGL?
my graphic card is very old and i believe that it does not support openGL.
with my favorite version of libreoffice, reading dialogs works as expected
without any problem in screen review.

Version: 5.3.4.2
Build ID: f82d347ccc0be322489bf7da61d7e4ad13fe2ff3
CPU Threads: 2; OS Version: Windows 5.1; UI Render: default; Layout Engine:
old; 
Locale: fa-IR (fa_IR); Calc: single
i should mention that the user interface of my libreoffice is enUS.
God bless you!
