Unsupported format when using 10bit color output

[p4block]

On sway 1.7 you can finally select 10 bit instead of 8bit output. Trying to screenshot with the grimshot script built into sway or with swappy emits the same error

/usr/share/sway/scripts/grimshot copy area
unsupported format 808665688

grim -g "$(slurp)" - | swappy -f - 
unsupported format 808665688
unable to load file: /tmp/swappy-stdin-O793E1.png - reason: Image file “/tmp/swappy-stdin-O793E1.png” contains no data

Thankfully the error goes away if I return to 8bit color output :smile:
