Errors and warnings not cleared in repl after reload

A few days ago repl window in Emacs stopped being cleared on reload. Everything works fine, just errors/warnings are displayed one after another until I manually clear the repl window.

Tried using `.emacs.d` backup from a few weeks ago (when all was fine), but issue holds.
I tested also with minimal (no other packages except `use-package`)

````emacs
(use-package haskell-mode :ensure t
:config
(add-hook 'haskell-mode-hook 'interactive-haskell-mode)
(use-package haskell-interactive-mode)
(use-package haskell-process)
)
````
and nothing.
So, very likely something got upgraded in my system, but haven't noticed anything (what I think could be) "related".

Using Arch, Emacs 26.2, haskell-mode 20190606.2028, stack 1.9.3, ghc 8.4.4 and 8.6.5

Anyone experienced this issue or maybe has a solution?
