<pre>Description:
scrolling down a column pressing <pg-down> with pressed <shift> key
simultaneously to mark a range, has far different performance in different
versions:
6.2.8.2: ~30.000 rows in about 20 sec.,
7.0.0.0.a0+: only ~8.000 rows in the same time,
imho a remarkeable regression / loss of performance ...
6.2.8.2 looks having better ui-performance in plenty respects, e.g. also
handling of comments, which didn't make it into subsequent versions ... :-(
Steps to Reproduce:
1. get a stopwatch at hand,
2. meter your mileage marking a big range on a sheet,
3. repeat with different versions of LO,
4. include ver. 6.2.8.2 winx64,
5. compare results,
Actual Results:
slow ui performance in ver. 7.0.0.0.a0+
Expected Results:
performance in fresh versions as good as in older ver. or better,
Reproducible: Always
User Profile Reset: No
Additional Info:
