Issues with PS-110.44

1. after a while(!) renaming stopped worked: placing the cursor inside a desired variable I see all occurencies being highlighted, but only the first one is getting renamed
2. after a while(!) tabs whitespaces are being inserted as spaces inside of if-block when I hit Enter

all of mentioned above is occured in php context

PS: and one more. I always get this in notification area:
