If you only read KePubs then you might want to edit the `My 15 line spacing values` patch to remove some of the low line spacing values and add some more high ones. There is a note at the end of the patch about this.

Increasing the line spacing didn't help.

On 3.18 i did not have this problem, yet i used your 15 line patch without any changes:

Let me see if you changed anything in those value's from 3.18 to 3.19..

..apparently you did, ill change the values back as they were in your 3.18 patch and see if that fixes it.

/edit: now i think about it, i [s]might[/s] have changed those values myself in your 3.18 patch.

/edit 2: editting the values to slightly higher ones did fix the problem. Cheers!
