Overlapping glyphs in the edit view

Hello, I’m using Glyphs 3.3 (3321) on MacOS 15.0.
I’m designing a vertical writing font with a different height (H) for each glyph.
When writing text in the Edit view set to the vertical mode, some glyphs overlap even if both are within their own bounding boxes.
I want to know how I can fix this problem.

Thank you.

Could you send me a sample font?

This is a sample font that is causing the problem.
sample.glyphs (8.8 KB)

I’ll have a look. In most CJK fonts I’v seen, They have ascender=800 descender=-200. That is what Glyphs kind of expects. I’ll see if I can fix this.

The overlapping issue still happens even after changing the metrics to what you’ve said.
Is there any workaround method currently available?

No, I need to fix this and upload an update. Probably tomorrow.
