            Bug ID: 162164
           Summary: Content is not rendered correctly after scrolling
                    horizontally
           Product: LibreOffice
           Version: 4.4.0.3 release
          Hardware: All
                OS: Windows (All)
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Calc

Created attachment 195460
  --> https://bugs.documentfoundation.org/attachment.cgi?id=195460&action=edit
Example file from Calc

Attached example file contains simple formula and many columns are filled.
There are some simple macros also, and with disabled macro support the issue
does not occur.

When the sheet is horizontally scrolled a lot left and right, the bottom
numbers become somehow incorrectly rendered.

1. Open attached file, and have macro support enabled
2. Scroll down to the row 52, then scroll left and right and left a lot
-> Numbers in the row 52 start to be incorrect, they should match the ones in
row 8.

Problematic behavior changed a bit in 7.5, before a few cells were repainted on
clicking on the sheet, but after this commit there is no such repaint:

tdf#152094 don't attempt scroll paint optimization for devices with a mapmode

Original problem seems to have started in 4.4 in the bibisected range:
https://cgit.freedesktop.org/libreoffice/core/log/?qt=range&q=f785c166bd80a4c9f50e6c4f7811bfd7ece16c81..6182437f8312e5823b3c9022993730428e572667

of which several seem to be relevant. Before this the values have changed
during horizontal scroll, but were refreshed when the mouse button was
released, so returning to that could be helpful.

Version: 25.2.0.0.alpha0+ (X86_64) / LibreOffice Community

Seems to be also Windows-specific.
