The full color mode is described by the string "Full (all available colors)" and when translated to Dutch it overflows the frame.
On simple solution is to remove the word "available" which would change the translation from:
Alles (alle beschikbare kleuren)
Alles (alle kleuren)
or all together, remove all descriptions for color mode:
o Full (all available colors)
o Medium (256 colors)
o Low (64 colors)
o Very low (8 colors)
o Very low
Fixed in tlcient now. What remains:
* This screenshot in our documentation needs updating:
* Fix for options in vncviewer, upstream:
Vendor drop of TigerVNC has now been done.
Looks good. Checked both tlclient options and vncviewer options, as well as the documentation.
