+Subject: [PATCH] Disable the seccomp sandbox
+References: boo#1174448
+
+In the referenced bug, it somehow fails to make the created context current,
+so no GL vendor detection is performed and it is assumed to not be Nvidia
+or on Wayland. This breaks rendering.
+While it would be enough to only disable the sandbox in this particular case,
+it's planned to drop sandboxing anyway
+(https://invent.kde.org/plasma/kscreenlocker/-/merge_requests/9) so just do the
+same here, just in a simpler way with less side effects.
