Description:
I just updated LibreOffice. The bottom part of the DFKai-SB font (Taiwanese kanji) I entered in Calc has disappeared.

Steps to Reproduce:
1. Open Calc or Writer
2. Select DFKai-SB font
3. Type 我不是臺灣人

Actual Results:
All characters except "人" seem to have the bottom part missing.

Expected Results:
It would be great if the bottom of the DFKai-SB font could be displayed properly.

Reproducible: Always

User Profile Reset: Yes

Additional Info:
It would be great if the bottom of the DFKai-SB font could be displayed properly. There was no problem in the previous version.

Suggests a corrupt font metric with the DFKai-SB (Kaiu.ttf) (Microsoft "Feature on Demand" from the 'Chinese (Traditional) Supplemental Fonts'). 

But if it had been behaving in prior builds, some recent change to calculating optimal row heights could be cause. So would need bibisecting.

@Jonathan, are you set up with on Windows with a zh-TW locale, or have the font loaded for jp-JP locale to have a look?

For original poster:

Please copy and paste the Help -> About dialog details.

Also please attach a sample document with DFKai-SB font. A document with the cell content using that font is being clipped.

I was able to reproduce this bug, but only on Windows with Skia disabled.
