Note that OpenKneeboard has NO WARRANTY, and anti-cheat software could theoretically have issues with it
WARNING: Anti-Cheat
While OpenKneeboard is not a cheat, it does hook into the games rendering and input pipelines, which over-eager anti-cheat systems may consider ban-worthy. While this is similar to how other overlays work (e.g. Steam and Discord), it is possible that using OpenKneeboard may lead to an anti-cheat ban.
As of March 19th, 2024, the developers have not received any reports of any users receiving any bans in any games, but this remains a theoretical possibility in the future.
Note that OpenKneeboard has NO WARRANTY; see the LICENSE file and full text of the GPLv2 for details.
