# parskip=half garbles sometimes pages

I am making documents with the option parskip=half. I have observed, that I sometimes get garbled pages, where I have no explanation for. I would expect a problem inside of Tex or Latex. With some help, I could boil down the problem into this MWE. Page 2 has text and tables unreadable.

I want to show this problem in order to get a solution one day. A workaround is not the question, I got already one. What could be buggy?

• I do not know the reason for this problem, but it may be relevant that it disappears when you remove the h specifiert from the floats. – schtandard Mar 21 '18 at 15:18

• @Ulrike Fischer, Thanks for the link. So this problem is known since 2010 and not solved in 2018, it seems to be a difficult one. – ulrichb Mar 22 '18 at 12:42
• You could add a comment to ask if there are news... – Ulrike Fischer Mar 22 '18 at 12:45
• In my experience, one is never "in need" of the h option. You are of course free to choose to use it, but usually using it defeats the purpose of the float environment (as you mentioned yourself, a minipage may be better suited). If you have so many floats, the p option may be useful as well. That said, have you tried the workaround mentioned in Ulrike's link? – schtandard Mar 22 '18 at 14:49
