Weird trails on go board after placing a few stones

Hi, there are some weird trails in the go board after I place and redo a few stones in a review board.
At first, I thought that my screen is not clean, but my screen is clean. If I change the board theme by selecting the custom theme and then select back to old theme, the trails gone.

How to reproduce the issue

I am not sure. This is the second/third time I’ve seen this issue. Maybe you could:

It looks like other folks are seeing this too (sometimes as smudges, and other times as straight lines). This issue has also appeared in the past, but was fixed. Hopefully a similar fix can be applied.
