            Bug ID: 142815
           Summary: When silde be shown with Hi-dpi enabled, some fonts
                    will bewrongly displayed
           Product: LibreOffice
           Version: unspecified
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: UNCONFIRMED
          Severity: minor
          Priority: medium
         Component: Impress
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: someborday at 163.com

Description:
When silde be shown with Hi-dpi enabled, some fonts like MS-Yahei will
bewrongly displayed. This may be limited to CJK True Type fonts. (For example,
Noto Sans CJK and Arial will be OK.)
Case 1) Numbers and English letters will be scaled. Some Chinese characters
will also be scaled. But other Chinese characters will NOT be scaled.
Case 2) Numbers and English letters will NOT be scaled. Some Chinese characters
will also NOT be scaled. But other Chinese characters will be scaled.
When I say "something will not be scaled" above, they will be smaller but the
space they occupy will NOT be smaller. That is, "abc" might be displayed as " a
 b  c ".
If you disabled Hi-dpi, it will be fine. When previewing, it will be fine.

Steps to Reproduce:
1. Make sure Hi-dpi enabled. You might check it in GNOME settings.
2. Open a *.pptx or *.odp file. (With CJK True Type fonts like Simsun)
3. Press F5 (or Shfit+F5) or click 'Start from first slide' (or 'Start from
current slide')

Actual Results:
1.
2. it seems normal
3. something wrongly displayed

Expected Results:
Something will be wrongly scaled. (See description)


Reproducible: Always


User Profile Reset: Yes
