We're currently running the latest release candidate of Lemmy 18.2. It has many fixes; however, there are still some remaining issues.
One example is that some buttons do not appear correctly on the dark themes. I will keep my custom dark theme as the default theme for now. I think it just looks better, even with broken upload buttons. I will attempt to apply a fix to it later today.
If you see any other issues, please, let me know so I can forward them to the core development team-- if you don't wish to do so yourself.
Thanks a lot! -jgrim
