Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal

Description:
The disk access when scrolling through a document containing PNG has
intensified heavily since the LibO4.2 series.
1. Lib4.2 doesn't have any disk activity at all (dconcerning tmp files)
2. Lib4.3 does have loads of reads when scrolling the file for the first time
to the bottom. After the initial loading scrolling will normalize. However,
when the document is inactive (idle), it will reset (after a tmp file
read/save) (even with Autosave disabled) resetting the behavior (heavily disk
access at 'first' scrolling, but it will normalize again.
3. LibO5 always keeps reading/writing to tmp files while scrolling down and up
again. And feels sluggish.
Steps to Reproduce:
1.Open attached file
2.Monitor disk usage soffice.bin with Sysinternals Process Monitor and/or
Process Explorer
3.Scroll the document up and down
Actual Results:
Lots of disk activity
Expected Results:
Nearly no disk activity, similar to LibO4.2
Reproducible: Always
User Profile Reset: No
