AR:
 When I switch to a file type that uses external application, the icon of that application blinks
(i.e. disappears completely for 0.1s, then appears. That causes text twitching. You can see that
 on screencast, and also, the video conveniently stops when the blinking/twitching is "in the middle")

ER:
 Icons shouldn't blink. Text shouldn't twitch


Note:  When I select content type by clicking, it also happens
