In combination that looks like kscreen sends a request to KWin which is stupid. Resulting in KWin losing the OpenGL context and then epoxy crashing. So we have two problems here: one being the incorrect request from KScreen, the other the fact that KWin ends up with no context. Anyway looks to me like I can push at least this patch as it improves the situation.
