Description Todd Vance 2016-12-17 17:02:24 UTC
Description:
I have a 14 page document with three graphics images (300dpi each about half a page), and if I insert the character anywhere in the text and hit Backspace 5 times, say, the cursor will go back 5 characters, but it takes about 5 seconds for the characters to disappear, making editing nearly impossible

In addition, if I type moderately fast (about 40wpm), characters get left out of words.  I did tests to specifically ensure I was actually typing the characters, they were just not "received".

Steps to Reproduce:
1.  Use the document found here:

https://github.com/tdvance/GameStateMachine/blob/master/Assets/StateMachine/HowTo.odt

2. Scroll down to Page 2, Introduction, and place character in the middle of the paragraph

3. Hit backspace 5 times within about a second or two and watch it take time to catch up

4. In addition, type a few words at a moderate professional-typist pace; It does worse than take time to catch up; it leaves out characters.

Actual Results:  
Characters typed left out, slowness of updating 

Expected Results:
Instant update, and if that is not possible, at a minimum queue all that is typed and do not drop keystrokes.


Reproducible: Always

User Profile Reset: No--but I did do the following after Googling:

increase memory: graphics to 1024MB and 128MB per object, disable Java, ensure OpenGL enabled for all, exit, exit the quickstarter, then restart, and close other programs and repeat.

I tried this odt with LOO 6.4 and seems to work fast (I don't have to wait to write or delete)
