After a text selection, some pages may appear as black or may be
rendered partially. The page structure may also seem corrupted.
To reproduce on the
https://www.open-std.org/jtc1/sc22/wg14/www/docs/n3220.pdf
4 MB PDF file:
1. Type zathura n3220.pdf.
2. Type "a" (best-fit mode).
3. Type the Home key to go to the first page.
4. Select "INTERNATIONAL STANDARD".
5. Type the End key to go to the last page.
If the issue does not occur, try some combination of PageUp, PageDown,
Home and End (the issue may occur on other pages). Possibly, try again
from step 1.
The only way to get rid of them problem seems to restart zathura
(until it occurs again).
This is a regression: the zathura package 0.5.11-1 from stable behaves
correctly.
