<pre>Description:
Probably an implementation detail, but the CPU time spend for screen rendering
while typing has increased (not noticeable in daily usage) Likely doubled, but
not sure (hard the measure). It seems to spend more time with alpha bitmaps
handling.
Not sure what the impact is for a high res screen..
Steps to Reproduce:
1. Launch LibreOffice 5.4 or 6b2 or 6.1 alpha with Instrument using the time
profile
2. Start typing 4 rows of text.
3. Create also a time profile using Libreoffice 5.3.7.2
4. Compare both of the time profiles
* the 6.0 profile will be spiky/ 5.3. flatter..
* . Drill Down to SwRootFrame::PaintSwFrame(OutputDevice&, SwRect const&,
SwPrintData const*) const en compare the time spend while there.
5. Compare the results with LibreOffice 5.3.7.2
Actual Results:
It looks like more time is spend rendering
Expected Results:
The big question..
Reproducible: Always
User Profile Reset: No
