Created attachment 138729 [details]
The screenshot of the Font tab of the "Title" style in the first slide of the Progress template

Tested in Daily build (2017-12-28_10.01.02) and Chinese (traditional) locale (zh-tw).

The default templates of Impress provide poor default Asian fonts settings. 
Let's take the "Progress" template for example.

How reproducible: always
Reproduce Steps:
1. Install Daily Build and set the locale to Chinese (traditional) in Tools > Options > Language Settings > Language > Language Of "Locale setting" to "Chinese (traditional)" and enable Default Languages for Documents "Asain:" checkbox then seclect "Chinese (traditional)"
2. Press OK and restart
3. Open Impress and select any of the default templates, such as "Progress" for example here.

Actual Result of the styles in the first slide of the Progress template:
In the Font tab of the "Title" style:
    Western Text Font
    Family: Liberation Sans    Style: Bold    Size: 75

    Asian Text Font
    Family: 思源宋體    Style: Regular    Size: 24

In the Font tab of the "Outline 1" style:
    Western Text Font
    Family: Liberation Sans    Style: Regular    Size: 36

    Asian Text Font
    Family: 思源宋體    Style: Regular    Size: 24

Expected result:
1. Sans-serif font families should mapped to any 黑體/方體/ゴシック (Hei/Fung/Gothic typeface). In the case of zh-tw locale, it should map to the CJK_HEADING of zh-tw locale defined in VCL.xcu.
2. Serif font families should map to any 明體/宋體/明朝體 (Ming/Sung/Mincho typeface).  In the case of zh-tw locale, it should map to the CJK_TEXT of zh-tw locale defined in VCL.xcu.
3. The Asian Text Font "Style" and "Size" should be in coherent with Western Text Font Style and Size. If it is Bold and 75 points for Western Text, it is better to be the same for Asian Text. 

Bottom line:
Mostly all the templates have the problems on Asian Text Font Family, Style and Size. It is best to have a corresponding setting for each locale. If that cannot be done, just use the same generic font family (matchmaking for Sans and Serif fonts), the same style (Regular, Bold, etc.), and the same size.

PS. here is a brief view of the first candidate CJK font of zh-tw locale in VCL.xcu:
CJK_HEADING: 思源黑體 (Source Han Sans)
CJK_TEXT: 思源宋體 (Source Han Serif)
CJK_PRESENTATION: 思源黑體 (Source Han Sans)
CJK_SPREADSHEET: 思源黑體 (Source Han Sans)

All the impress templates use sans-serif fonts, so as no setting is defined in the template files, it should automatically pull the correct font based on VCL.xcu from CJK_PRESENTATION. But if a serif font is defined, i dont think there is a odf attribute that could be set that would cause LO to choose the correct font from VCL.xcu.

Maxim, Regina: thoughts?

As the cjk and ctl font size and weight isnt defined in the tag, i would have expected that it would utilize the same settings used in latin, so this likely can be fixed in code, or alternatively we could add style:font-size-asian, style:font-weight-asian, style:font-size-complex, and style:font-weight-complex attributes.

Actually, I found the "Vintage" template of Impress using Liberation Serif. BTW, many templates shipped in other office suites (such as MS Office and Apple Keynote) also use Serif in some Impress templates. So we still have to take Serif into consideration.
Comment 3 Laurent Balland 2017-12-29 11:18:53 UTC
"Progress" and some other Impress templates have been updated in 6.0.0 RC2
See https://bugs.documentfoundation.org/show_bug.cgi?id=103317#c26

Please check if sizes of Asian fonts are now correct.

This is tested in Daily build (2017-12-28_10.01.02). Not resolved yet.

Actually I removed all these tags, because I was expecting such behavior: use latin settings for size and weight with asian and complex.
This may be a different bug report.

Comment 16 Laurent Balland 2019-12-30 13:52:22 UTC
Can somebody using Asian or complex UI test in LibO 6.4.0RC1 if Progress template has now better rendering with correct font sizes?
If it works for Progress template, I will extend this patch to other templates.

Env:
Version: 6.4.0.1
Build ID: 1b6477b31f0334bd8620a96f0aeeb449b587be9f
CPU threads: 4; OS: Linux 4.15; UI render: default; VCL: gtk3; 
Locale: th-TH (zh_TW.UTF-8); UI-Language: en-US
Calc: threaded


Reproduce Steps:
  (1) Change the local setting.
  (2) Select the theme "Progress" from theme selector.
  (3) Open the font setting dialog for "Title".


Result: 
----------------------------------------------
If Local Setting is English (USA)
    Western Text Font: Libration Sans, Bold, 75pt
    Asian  Text  Font: DejaVu Sans, Bold, 75pt
    Complex Text Font: Noto Sans CJK TC, Bold, 75pt
----------------------------------------------
If Local Setting is Chinese (Trad)
    Western Text Font: Libration Sans, Bold, 75pt
    Asian  Text  Font: Noto Serif CJK TC, Bold, 75pt
    Complex Text Font: Noto Sans CJK TC, Bold, 75pt
----------------------------------------------
If Local Setting is Japanese
    Western Text Font: Libration Sans, Bold, 75pt
    Asian  Text  Font: Noto Serif CJK JP, Bold, 75pt
    Complex Text Font: TakaoPGothic, Bold, 75pt
----------------------------------------------
If Local Setting is Korean (RoK)
    Western Text Font: Libration Sans, Bold, 75pt
    Asian  Text  Font: Noto Serif CJK KR, Bold, 75pt
    Complex Text Font: Noto Sans CJK TC, Bold, 75pt
----------------------------------------------
If Local Setting is Thai
    Western Text Font: Libration Sans, Bold, 75pt
    Asian  Text  Font: Waree, Bold, 75pt
    Complex Text Font: Kinnari, Bold, 75pt
----------------------------------------------



Issues: 

  (1) Noto "Serif" CJK is used, which should be Noto "Sans" CJK.

  (2) Why a CJK font is used for CTL, when local is Western/CJK?

  (3) Regarding to Thai, "Kinnari" seems not a sans font?
Comment 18 Laurent Balland 2020-01-01 17:10:06 UTC
@Hiunn-hé: thanks for your tests.
Size, style and weight are now forced to be the same. These properties can be defined inside XML code of templates. Modifications of templates are on the way.

Unfortunately, I don't know how to fix font changing for the issues you mentioned.

CJK font fallback, it seems to refer to CJK_TEXT and not CJK_PRESENTATION in VCL.xcu. You can check this by following the steps below.

1. Open Options, Go to LibreOffice -> Advanced, Click "Open Expert Configuration".
2. Search for "CJK_TEXT".
3. Double-click on the Asian language you are using and add the SansSerif fonts to the top of the Value.
4. open the template from Impress Template.

It modified the color of the border on the 3rd slide from green to white. Was it done on purpose? I'm going to revert this addition.
