Created attachment 137925 [details] Screenshot showing the problem When using SAL_USE_VCLPLUGIN=default, LO 6.0.0.0-alpha1+ (git from today) works well - but checkboxes in dialog boxes are invisible. Seen on OpenMandriva Cooker (linux 4.14, glibc 2.26, current Xorg) running Plasma 5.11.3, no special theme selected.
This problem goes away when installing the "galaxy" style -- omitting that style in favor of breeze doesn't seem to be a good idea. Fixing in our packaging by making "galaxy" mandatory.
