Since I get hostile responses each time I say this on another site I shall not mention… It looks like BattleNet CEF patches broke again with Wine Staging 2.21 and the latest version of BattleNet…
Games like Overwatch still run pretty good at Very High priority, but it looks like all the CEF stuff broke again with an update to CEF… (Chrome Embedded Framework)
DON’T spread this information unless you are actually a bug tester and know what you’re doing, otherwise the internet will hate you. I’m only posting it to here to politely get it out there without being berated.
While the machine was still on the old BattleNet client briefly before updating, no CEF errors.
