Keypresses will randomly stop registering. I was sparring some friends earlier and we would be forced to a complete halt with our movement keys not working for a second or two. This also happens while typing.
Occasionally the back button on profiles will not work and it will change pages. Usually after clicking it 3-5 times it'll work again.
PMs and other UIs will repeat the last 8-10 characters or an error box. The previews in shops will not display.
The text box for typing messages is completely black. You cannot copy/paste into text boxes.
The overall performance of the client is slower. PC doesn't even reach 20fps. Flash did. Edit: Seems to be better now.
The check boxes in the settings/house/guild house/guild settings menu don't show up but you can still press them.
The heads in guild chat are squished. Error boxes also show in the names of guilds and guild mates.
Using the -/+ buttons at the top don't increase the header size.
Enabling the font change option makes chat text look a lot bigger than it use to.
The font in profiles/ui looks blurry, bigger and somehow squished now lol. Edit: Even fonts in statues are bigger now, making most people's organized statuses look jank (See Kai (Rare)'s status on iOS, then on PC).
Mixed GST is gonna be fun lol
