See https://github.com/linuxwacom/xf86-input-wacom/issues/178 Upstream has turned off gesture support by default due to various issues, but we still set it to on by default in our KCM, which then gets propagated by the KDED module. So once you install the package, gesture support is silently turned on, which breaks touch.
Working on this.

Git commit 3c10c7dfa865cb2cfd3ca6ed9c358b24689e5eee by Nate Graham. Committed on 06/08/2021 at 16:32. Pushed by ngraham into branch 'master'. Turn off gesture support by default and warn when turning it on manually Gesture support has been disabled by default upstream to work around an inherent incompatibility with Wacom-provided gestures and touch support in Qt; see https://bugreports.qt.io/browse/QTBUG-84756. However the KCM still has it on by default, and its KDED module propagates that change to effectively turn gestore support on automatically. This results in touchscreen touch being broken for all Qt software by default when this repo is installed. This commit turns gesture support off by default to match the new upstream setting and prevent broken touch support in Qt software, and also shows a warning message about this if the user turns it on manually.
