The documentation for the "Allow JPEG compression" checkbox [1] is confusing. Given the checkbox label, you would expect unchecking it to completely disable JPEG compression. However -- the TAG describes the checkbox as follows: > By selecting this option you choose to override the standard JPEG compression > quality of color-rich parts of the screen. This makes it sound like JPEG compression is always on, and checking the "Allow JPEG compression" checkbox only lets you pick a non-standard compression quality. It seems like the documentation was not updated when fixing bug 856 and still reflects the pre-bug 856 behavior. [1] https://www.cendio.com/resources/docs/tag/client_options_optimization.html
Note: When the unchecked, vncviewer is called with `-NoJPEG`.
