Created attachment 156204 [details] RTL annotation typing is slow and consumes high CPU Typing in Arabic takes long time for the letters to appear and if you type fast the whole Okular becomes frozen and starts to consume high CPU, and you should wait for several seconds to see the typed letters. See attached video for more info. NB: At random times, if you type quickly multiple RTL annotations, Okular enters a state of memory leak and you should kill the entire app to use it again.
