Consider the following MWE:


\title{The Title}
\author{My Name}
\institute{My Institute}


There is a white bar on the right edge of the box:

white bar with Noto Sans

The width of the white bar seems to be font dependent. If you replace \usepackage{noto-sans} by \usepackage{lmodern}, the bar is narrower:

white bar with lmodern

This is not a viewer issue, the white bar is also present on a printed page. I'm using MiKTeX. All packages are up to date.

How to fix this issue?

Note: There are other questions about broken shadows or white lines in beamer here on tex.stackexchange, but none seem to address exactly this issue.

    @UlrikeFischer I have now tried pdfTeX, XeTeX and LuaTeX. The result is the same for all three engines.

  • I can reproduce your error; then I update the package; and your code now produces no error

This bug was fixed in beamer version 3.64. It has been discussed at the GitHub page of the beamer project (see this issue).

If you compile the MWE using version 3.64, the shadow is fine:

(Unfortunately, according to the linked GitHub discussion, there are now new issues with shadows in other situations.)
