Welcome Screen

When started with SAL_USE_VCLPLUGIN=kde5 LibreOffice uses bolder fonts. It is noticeable in Welcome screen where user selects the new document type and regular dialog windows. I am attaching some screenshots for demonstration and comparison with regular KDE apps.

Distro: Arch Linux
LibreOffice: 6.3.0.0 Beta 1 AppImage
Qt: 5.12.3
KDE Plasma: 5.16
KDE Frameworks: 5.59

Can you please
* paste the version information from "Help" -> "About LibreOffice"
* check what happens if you use a current daily build of Libreoffice from [1]

You can install that one in parallel as described at [2]. It'd be interesting to know whether this also happens with that one. Might also be somehow related to the fact that you're using an AppImage version of LibreOffice.

The version info:

Version: 6.3.0.0.beta1
Build ID: a187af327633f5f00363be5131bd21a13e0f1a7b
CPU threads: 8; OS: Linux 5.1; UI render: default; VCL: kde5; 
Locale: en-US (en_US.UTF-8); UI-Language: en-US
Calc: threaded

It is the AppImage.


My distro is Arch. It doesn't have rpm or dpkg and their utilities. I tried downloading both .deb and .rpm versions of the latest build. .deb variant doesn't have any installer scripts and since Arch doesn't have dpkg-deb I cannot extract the packages. Maybe later I might write a script that extracts using ar and tar.

For .rpm variant, It provides a script to install locally but it tries to run rpm which Arch doesn't have either. I can get rpm2cpio utility from the official packages and try the Step 3 but it results in weirdly named folders in the screenshot.

Debian even testing have really old packages, especially KDE plasma which is a very quickly moving target and others like Qt, freetype2 and fontconfig; all 3 of them had some important changes in recent releases.

In the meantime maybe somebody using openSUSE Tumbleweed may help. It is also a rolling-release like Arch and uses rpm.
Comment 6 Ongun Kanat 2019-06-16 00:02:53 UTC
BTW This happens with Libreoffice 6.2.4 too. It is the official package in the Arch repos.

Version: 6.2.4.2.0+
Build ID: 6.2.4-1
CPU threads: 8; OS: Linux 5.1; UI render: default; VCL: kde5;

The screenshots are the same. Slightly bolder fonts in KDE5 VCL.

Alternatively, you could also download a debug build, which is provided in simple archive format at https://dev-builds.libreoffice.org/daily/master/Linux-rpm_deb-x86_64@86-TDF-dbg/ (larger download and runs slower, though).
It may well be that the result will be the same there, though, as with the versions you already tested.

It is the exact same situation with debug package.

I have it tested with the latest non-debug daily build. It is the same.

Comment 10 Xisco Faulí 2019-10-22 14:31:52 UTC
Hello Ongun,
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

Screenshots for 6.4 alpha1

I downloaded the latest build (2019-10-27_22.29.11) in [1] and extracted it as instructed in [2].

The soffice binary created a separate configuration directory in ~/.config called libreofficedev but I moved out my libreoffice folder in order to eliminate the possibility of any corruption and deleted libreofficedev folder after each trial. 

The bug was still there in each run without any exceptions. I also took screenshots of the menus in order to show the difference between Qt rendered main menu and LibreOffice rendered context menu and I include an overexposed version of two menus. Again the bug can be observed in welcome screen as well. I include 4 screenshots as the attachment.

I will also upload my fontconfig config files. Maybe they can shed some light. However, I don't think my font configuration is terribly wrong (it's a bit hacky for emoji though) since the LibreOffice and KDE VCL is the only UI with unusual bold fonts I get in my computer. All the other GTK{2,3} and Qt 5 apps render perfectly normal fonts.

Furthermore I will try Manjaro live CD and put a report.


The version info is below:

Comment 13 Jan-Marek Glogowski 2020-03-08 21:00:00 UTC
On 2020-03-04 https://gerrit.libreoffice.org/c/core/+/89797 was merged into 6.4 and a day earlier into 7.0.

The kf5 backend had some incomplete conversion table from Qt5FontInfo::weight() int to LO VCLs FontWeight enum. Maybe this fixes your problem. Still LO uses an enum with the values defined by HTML CSS and Qt5 uses some larger int range, so it can't really match perfectly.

This fixed the bold fonts for the qt5 backend, because that wasn't handling FontWidth / stretch at all, but this shouldn't affect kf5 / you at all. Still worth a try.

I downloaded latest mater build and tried it. Problem seems to be NOT solved. Moreover the fonts seem to be turned white (it might be KDE originated problem though). I will update the screenshot.

Hmm - there was a MacOS change, which - for whatever reason - changed some of the colors in the qt5 plugin in

But I don't get the white colored font :-(

Can you try to use a new user profile with soffice  -env:UserInstallation=file:///tmp/test

Maybe your profile is somehow broken - no other idea...
