UI regressions in "gen" plugin with LibreOffice 6.1

[Rene Engelhard]

Hi,

I got

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=904598

(contains a screenshot)

and

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=905408

lately.

It seems that there were UI problems introduced in the gen VCLPLug
in 6.1? I cross-checked with gtk3 when replying to those bugs, and gtk3
doesn't have both problems.

Any idea? Probably too late for 6.1.0 anyways, but this should be fixed
for 6.1.1 I think :-)

Regards,

Rene
