image_view causes 100% CPU usage

[rursprung]

when i run image_view (using ros2 run image_view image_view --ros-args -r image:=/my/image) for 1-2 topics then the CPU usage goes up to 100%. i've tested this on several devices, all with the same result.

this is with ROS jazzy, image-view version 5.0.5 from apt (5.0.6 hasn't been synced to apt yet, but based on the commits it doesn't include anything relevant for this)
