            Bug ID: 119362
           Summary: Very slow horizontal scrolling in Calc
           Product: LibreOffice
           Version: 6.2.0.0.alpha0+ Master
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Calc
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: shitpoet at gmail.com

Description:
The horizontal scrolling (either my mouse or by keyboard arrows) is very slow
in Calc when a specific cell with long (over 8k chars) html-like text becomes
visible. The app freezes for several seconds.

Steps to Reproduce:
1. Open attached file in LibreOffice 5.3, 6.1 or 6.2-alpha
2. Scroll to the right using keyboard to a column AE ("*Description")

Actual Results:
The app freezes for several seconds (around 7 seconds on my laptop). While the
app is frozen the screen is distorted (partly scrolled). When the app becomes
responsive again, it correctly draws the screen. 

Expected Results:
Scrolling to the right without freezes, like with other cells.


Reproducible: Always


User Profile Reset: No
