Unfortunately adding these hooks doesn't fix issue:

(add-hook 'pre-redisplay-function #'hl-line-highlight nil t)
(add-hook 'pre-redisplay-function #'hl-line-maybe-unhighlight nil t)
(add-hook 'pre-redisplay-function #'global-hl-line-highlight)
(add-hook 'pre-redisplay-function #'global-hl-line-maybe-unhighlight)

These two functions are used in `hl-line.el'.
I've tried pre-redisplay-functions hook as well with no effect.
