Ubuntu Phone 15.04 (r23) [mako]

I jumped from ~r15 to r23 and lately have a vague constellation of
symptoms that seem to relate to slow processor, memory, or display.
Unfortunately, I have not discovered where to correctly file this bug.

 - Password to unlock phone often fails due to missed key or confirms keys pressed ~3 seconds after I touch screen
 - Scrolling web page on Browser suddenly locks, after two or three swipes with no response, screen then shows bottom of page
 - Rotating phone from landscape to portrait and back, often a stretched screen or fuzzy screen appears
 - In Contacts, looking for name toward middle or end of alphabet, I swipe down and touch "M" and it goes to first name with "M" and then a second later reloads Contacts to first name with "A" and I have to swipe down and touch "M" again before I am able to select name
 - When I touch button to wake up a locked phone, nothing happens, I then touch again and the password screen appears momentarily and then returns to black, and I have to touch third time to finally load password screen and enter password

Title:
  Passcode screen misses keypresses

Status in Canonical System Image:
  Fix Released
Status in ubuntu-keyboard:
  Invalid
Status in unity8 package in Ubuntu:
  Fix Released
Status in unity8 package in Ubuntu RTM:
  Fix Released

Bug description:
  For some reason the passcode entry screen / lock screen feels very
  laggy when entering my passcode.

  It frequently misses my keypresses, so i end up typing insufficient
  characters. I don't know if the hit area for the numbers is too small
  and I'm mis-hitting or if there is a lag/delay. I'm not typing
  stupendously fast, but pretty quick. Any slower and it feels very
  deliberate, like I'm typing a PIN into an ATM.

  ====

  To test:
  - start an app
  - lock the phone
  - resume
  - swipe the greeter away
  - verify that the app is suspended ("T" in ps x | grep) until you type the correct passcode
