Hey, GhostRain! It sounds like either hardware acceleration is causing an issue or with the disconnections, there’s a bandwidth issue.
Let’s try disabling hardware acceleration for the Blizzard Application. In the App, go to Settings (Blizzard Logo at top left), then under general, scroll all the way down to Advanced Settings and uncheck “Use browser hardware acceleration when available.”
Browsers will also have this setting, but the location will vary depending on the browser. If it continues, try disabling this setting for the browser.
Hopefully this helps!
