Description war 2019-02-10 12:58:32 UTC
Description:
Configuration:
Ubuntu 18.10, MacBook Pro Retina 13" (HDPI 2560x1600)
LibreOffice 6.1.4 (repo) and LibreOffice 6.2 (AppImage).

Several components of LO are rendered blurred:
- Toolbar icons
- Embedded OLE components
- Embedded images
- Table frames

Under Ubuntu 18.04 (LTS) LO 6.0.3 (from repo) did not show this.

The 6.1.4 AppImage did not show it either.
6.2 AppImage does not honour the installed theme (which LO 6.1.4 (repo) and 6.1.4 AppImage do).

Seems like a recursion bug related to screen rendering in LO

Steps to Reproduce:
1.Create a table in Calc
2.Embed in Writer as OLE
3.View results on screen

Actual Results:
Embedded objects are blurred
Toolbar and icons are blurred
Text in embedded objects is barely legible

Expected Results:
A sharp and crisp display (as was in LO 6.1.4 AppImage or 6.0.3 in Ubuntu 18.04)


Reproducible: Always


User Profile Reset: Yes



Additional Info:
I reported this serveral times on Canonicals Launchpad bugtracker.
The issue was closed every time with no improvement.

As this does not happen on Windows or MacOS the problem seems bound to Linux and HDPI displays (which will be ubiquitous in the future)

LO 6.1.4 repo

This image demonstrates correct theme but blurred icons and embedded documents (OK its thumbnails here but the result is the same)

LO 6.1.5 AppImage

This image demonstrates correct theme and correct icons and embedded documents (again thumbnails here but the result is the same)

LO 6.2.0 AppImage

Here the theme is incorrect (default) and the icons and thumbnails are blurred.

There is something regressing with alternate versions in the way you display content.
Comment 4 war 2019-02-12 17:44:20 UTC
The images demonstrate what I mean by "blurred" and "wrong theme"

I use a themed Gnome as one can see
Comment 5 war 2019-02-12 17:45:50 UTC
Just to prevent the question (Have you tried turing off custom themes):

Yes the same situation applies with both Yaru (new Ubuntu theme) and Ambient (old Ubuntu theme)
Comment 6 miltonh26 2019-02-15 04:26:07 UTC
Same for me except for 6.1.5.2 on Kubuntu 18.10 using DEB files. Fonts and toolbars were not rendered properly, thus LO was unusable. Before that tried 6.2.0.3 (also with DEB files) but had the same issue. Also attempted deleting configuration files and the issue was not corrected. Ended up reverting to the repos and reinstalled 1:6.1.4-0ubuntu0.18.10.1 which works well.

A new major release of LibreOffice is available since this bug was reported.
Could you please try to reproduce it with the latest version of LibreOffice
from https://www.libreoffice.org/download/libreoffice-fresh/ ?
I have set the bug's status to 'NEEDINFO'. Please change it back to
'UNCONFIRMED' if the bug is still present in the latest version.

I have confirmed that this issue is still happening on LibreOffice 6.2.5.2. I am running Ubuntu 18.04.3 LTS. Here is a screenshot of the bug:

So we have different issues here. The mac issue in 6.3 is reported in bug 122218.
However, this one is on Linux...

@Xisco Faulí

https://www.libreoffice.org/download/libreoffice-fresh/ redirects me to https://www.libreoffice.org/download/download/

On that page there is a link to prerelease: https://www.libreoffice.org/download/download/?type=mac-x86_64&version=6.4.0&lang=en-US - is this the correct build to test?

Comment 20 war 2020-07-20 08:08:24 UTC
I'm afraid that this bug still exists (in 6.4.5.2).
Several dialogs provide blured fonts (the main documents are clear though).

The dev team seems to still use outdated build environment.
Current versions:

XCode: 11.6 (12.0 for developers)
MacOS: 10.15.6

Which information do you still require?

Here is a screen shot from the Start Centre. The thumbs are blured, and some dialogs switch to blured when worked on (most notably tabed dialogs and regularly if LO is moved between monitors).

Comment 24 samarthupadhya2309 2020-11-12 01:04:43 UTC
I could reproduce the bug. The text was very slightly blurred out and everything else looked fine. The text was the only issue for me and it also look like the text color had also gotten a little bit lighter. It is still readable but it was a little bit more blurry than usual. I am still going to keep it at Unconfirmed though because the toolbar and icons were just fine only the embedded text got slightly more blurry than should be.

Texts are blurred with 7.4.23 AppImage on Ubuntu 22.04

I could confirm that the bug still exists with AppImage version 7.4.23 on Ubuntu 22.04. Please see the attached screenshot.
Comment 30 Stéphane Guillou (stragu) 2023-03-28 11:47:58 UTC
I marked a few comments as off-topic, especially regarding a fixed macOS issue.
Let's keep this focused on blurriness with GTK3.
