@NiLuJe I've been testing it by setting just one image and the issue persists. Also those screenshots used to work properly years ago and all are of the same resolution.
Edit: Also suddenly (I've needed to deregister and register the device) I started
getting this when trying to access KUAL.
Edit 2: it's ok again, after restart. The issue with screenshots persists. Could it be because of "kual-gawk-1.5.N" installed? if so, how do I remove it?
