Good afternoon from balmy Hawaii! I came up with a fractal at 3840x2160 (4K resolution) that I saved and would like to reload and render in a 30000x30000 disk video mode but when I pick that disk video mode selection to change the mode, generate it, and save the resulting image, it's only 3840x2160 resolution. Running SDL2-Xfractint-20.05alpha-2021-07-03.tar.xz downloaded from fractint.org/experimental on 64-bit Debian 11, i9 processor with 64GB of RAM and 780GB of disk space free, so neither memory nor disk space should be a limitation.
