Bug ID: 157015
Summary: Super slow performance/navigation in Calc when hiding
all unused rows and columns in a spreadsheet
Product: LibreOffice
Version: 7.6.0.3 release
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: Calc
Assignee: [email protected]
Reporter: [email protected]
Description:
I want to only see used rows+columns in a spreadsheet. Therefore, I select the
rest of the rows+columns and hide them. But this makes Calc performance to
degrade greatly: scrolling with gestures/scrollbar takes more than a second for
each UI update/refresh, cell navigation with keyboard isn't instant (unlike
when a huge number of rows+columns isn't hidden).
I use Debian-based OS (with DEB packages) and GNOME DE (haven't tried KDE yet).
Steps to Reproduce:
1. Select all unused rows and hide them.
2. Select all unused columns and hide them.
3. Try to scroll through visible/used rows/columns.
Actual Results:
Very slow overall performance, lags.
Expected Results:
Smooth scrolling, quick cell navigation, no lags.
Reproducible: Always
User Profile Reset: Yes
