When I have something(text) selected the cpu load gets 100%.
Scrolling and hiding the selection does not change the situation.
When focus is changed to another window cpu load goes to 0%.
When focusing again on Xreader(which has text selected) cpu load rises again.
Clearing the selection makes cpu load lower to 0%.

Occurs on Xreader 1.0.8
