Hey, thanks for the report and the screen recording. That makes it easy to confirm.

This is a known bug with table rendering in the Markdown preview. The team is aware and tracking it. There’s no ETA for a fix yet, but your report helps us prioritize.

Unfortunately, there’s no workaround right now. The flicker happens because the table column resize handles trigger a layout loop when you hover.

I’ll update here if there’s any news.

Just to add: this makes it pretty much impossible to copy the table
