<pre>Description:
It's a bit of nitpick, but I'm still wondering what's where all the CPU power
is going while typing plain text with every writing assistance I know of
disabled.
While typing normal words fast the CPU is in a range of 0,78 - 1,15% (LibO
5.4.0.0b2). Mostly hitting 1,15%
When doing the same with LibO 3.5.7.2 or 4.3.7.1 the range is 0,38-0,78 (mostly
0,78)
Going back to LibO3.0.0. CPU usage is mostly is in a range 0,0 and 0,38%
Doing the same by typing gibberish makes it worse way worse (3.8% - 6.00% with
LibO5.4.0.0.b2)
Steps to Reproduce:
1. Use a build without dictionary's
2. Disable Autocorrect while typing (Tools -> Autocorrect)
3. Options -> Language Settings -> Disable writing aids
4. Open Process Explorer
5. Start typing into an empty document. Play with the keyboard: Press random
letters with combined with spaces and enters. Monitor CPU usage. Typing regular
words is also an option when typing quickly
Actual Results:
More and more CPU cycles are needed for just plain typing.
Expected Results:
Most ideally the same behavior as with 3.0.0
Reproducible: Always
User Profile Reset: No
