From d67ba3ea65717ceab3e0c91267191c6ed2aac2c2 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Jonas=20=C3=85dahl?= Date: Fri, 10 Jul 2020 09:06:33 +0200 Subject: screen-cast/src: Remove follow up timeout source on disable We failed to remove the timeout source when disabling, meaning that if a follow up was scheduled, and shortly after we disabled the source, the timeout would be invoked after the source was freed causing use-after-free bugs.
