Mouse cursor disappeared on external display when rotated

Installed 10.13.5 release today, and it's fixed!

I actually just solved that problem on my Macbook Pro.

Tried all possible solutions. What worked was to make the cursor bigger. However, depending on your screen resolution you will need to play with different sizes.

There is a discussion in Apple forums with more details: https://discussions.apple.com/thread/8342495

I installed the macOS 10.13.6 beta today, and it appears to have fixed the issue. If it recurs later today I’ll update this answer.

If you make cursor bigger, in the editable mode, a cursor is disappearing again. But if you change the cursor size even more (for me it's almost a half of that bar), it will appear! But the size is so big now, it looks very funny on my screen.
