After changing from Page View to Web View

FORMATTING

- Open a document in Page View
- Do Format / Page Style / Transparency
- Select Tranparency 80%
- OK
- Do View / Web

The document display is corrupted.
The 'Page View' version is displayed as well as the 'Web View'.
Comment 1 Dieter 2020-05-28 06:59:52 UTC
I've tried to reproduce it, but I couldn't see any difference in page style after changing transparency to 80%.
Comment 2 Dieter 2020-05-28 16:01:55 UTC
Now I've recognized, that transparency affects page area. So it's the expected result that nothing happens after changing transparency with no special area settings.

To be certain the reported issue is not related to corruption in the user profile, could you please reset your Libreoffice profile (https://wiki.documentfoundation.org/UserProfile) and re-test?

I have set the bug's status to 'NEEDINFO'. Please change it back to 'UNCONFIRMED' if the issue is still present.

ps - the problem is still the same in safe mode.
Comment 7 Simon 2020-05-30 21:54:02 UTC
?? what happened to the text I wrote??

Here it is again! - the steps to reproduce this in more detail:

- Open a document in Page View
This is the first screenshot.

- Do Format / Page Style / Transparency
- Select Tranparency 80%
- OK
My screen still looks like the first screenshot.

- Do View / Web
Now my screen looks like the second screenshot. It seems to me that 'Web View' has been overlaid (instead of replacing) 'Page View'). Note the shadowy text and the the text down the left side of the screen.

If I scroll down using the mousewheel, then the page becomes more corrupted - as in the third screenshot.

I have tried this on a laptop and desktop PC - the same results.

Comment 13 Simon 2020-12-13 17:02:23 UTC
I can regularly repoduce this bug in safe mode.
(now using 7.0.3.1 - I originally reported this in 6.4.3.2)

Here are the steps:

- open in safe mode
- File / New / Text document
- Enter the text "This is a test document."
- Copy and paste until the document is more than one page long.
- Format / Page style / Transparency
- Change Transparency to 100% and select Ok.
- View / Web
>>   Document shows on screen as in 'Corrupt display of file - 1'
- Mousewheel down and up
>>   Document shows on screen as in 'Corrupt display of file - 2'
If you resize the window, the document is redrawn and displayed correctly. But as soon as you move down the document using the mousewheel or scroll bars, it is corrupted again.
Comment 14 Simon 2020-12-13 17:12:09 UTC
It seems to me that the bug appears when the document is longer than one page.
If you start with a short document, it's ok, but then adding in extra lines corrupts the display:

- open in safe mode
- File / New / Text document
- Enter the text "This is a test document."
- Format / Page style / Transparency
- Change Transparency to 100% and select Ok.
- View / Web
>>  Document displays ok.
- Add more lines until the document is more than one page long.
>> Document display is corrupted.
Comment 15 Dieter 2020-12-16 18:26:06 UTC
I confirm it with

Version: 7.0.4.2 (x64)
Build ID: dcf040e67528d9187c66b2379df5ea4407429775
CPU threads: 4; OS: Windows 10.0 Build 19042; UI render: Skia/Raster; VCL: win
Locale: de-DE (de_DE); UI: en-GB
Calc: CL

and steps from comment 14 (no necessary to change to SafeMode)
