With a small --with-lang list, `make screenshot` executes rather 
quickly, and at least on Linux doesn't pop up any windows.  So the 
cheapest (in terms of coding) change to include it in 
<https://ci.libreoffice.org/job/gerrit_master/> would be

in lode.  (<https://ci.libreoffice.org/job/gerrit_linux_clang_dbgutil/> 
appears to build without an explicit --with-lang=... at all.)

If that is deemed too expensive, we could alternatively see to shoehorn 
an additional `make screenshot gb_SUPPRESS_TESTS=x` invocation into the 
build instructions for that job.

(That said, you can catch such issues locally with `make screenshot 
gb_SUPPRESS_TESTS=x`, and they are found post-integration by 
<https://ci.libreoffice.org/job/lo_tb_master_win_screenshot/> and 
<https://ci.libreoffice.org/job/lo_ubsan/>---the latter because that way 
it tries to increase coverage of code that happens to get executed.)
