I have similar problems on Code vs Zombies - didn't check others yet.
PC perfectly up to date, only thing that stands out a bit is 4k monitor - I've seen some apps behave strangely on this res.
Probably not in this case, errors are:
- Few 403's on jpg and png's
- 126 of "Possibly unhandled rejection: undefined undefined" from vendors.js
If you need more info let me know, I can provide it when I'm back from work.
