            Bug ID: 138356
           Summary: CALC Hyperlink button text corrupted with part of an
                    embedded graphic image
           Product: LibreOffice
           Version: 7.0.3.1 release
          Hardware: All
                OS: Windows (All)
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Calc
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: that.man.colin at gmail.com

Description:
Hi,
I need advice on how or even if to report an intermittent bug.
Established, reliable five sheet CALC document with Hyperlinks to online
spreadsheets which are accessed, select copied and pasted (sometimes enforced
special) to the target sheets.
Recently updated to 
Version: 7.0.3.1 (x64)
Build ID: d7547858d014d4cf69878db179d326fc3483e082
CPU threads: 4; OS: Windows 10.0 Build 19041; UI render: Skia/Raster; VCL: win
Locale: sv-SE (en_GB); UI: en-GB
Calc: threaded
Three of five hyperlinks have the button image corrupted "randomly" - the
corruption is part of an embedded image on the second sheet which simply
replaces the text on the affected buttons, although the control properties
retain the original text definitions.
The corruption does not affect buttons "preceding" the image - only those in
the subsequent sheets.
I now believe it may be a result of the start process although originally I
noticed it following website access.
My perception has now changed because last night 21:30 it was saved in perfect
condition. First access this morning it is corrupt with zero processing or web
access.
The "repaired" file functioned normally over two days and about 30 "button" web
accesses.
Are hyperlinks somehow "verified" on startup?
I previously wrote a highly detailed report with "clean" & "corrupted" example
attachments together with detailed process instructions and then it failed to
misbehave so I abandoned it as "not easily reproducible".
Today, just the simple process of opening it triggered button image corruption.
How should I proceed?
Should I submit clean and corrupt versions of the file for somebody to
periodically open and inspect?
Are you able to monitor code execution with a debugger?
Whilst it's really only cosmetic, I feel it is symptomatic of something far
more significant - Would you disagree?
