When checking the error report section of my game, I came across this bug and it was not linked to any of my scripts.
Expected behavior
I found it strange since I didn’t use any UISizeConstraints in my game. Just to be sure, I used a script in an attempt to find any UISizeConstraints in my game and as expected, there were no results. I also used the “Find All” feature in studio and it was unsuccessful.
try using the Find keybind in studio (ctrl/cmd + shift + F) and searching for UISizeConstraint. a script might be creating one.
I forgot to mention that I tried that as well 
did you try disabling all your plugins? if any?
It’s a bug that seems to only replicate in game for some players. I’ve never encountered this error when playtesting in studio.
I’ve been getting the same bug, it shows twice in client console in game too. Happens in other games i play also
Thanks for your report, we could not reproduce this.
Could you provide a test place where this happens ?
I’m pretty sure this happens with all(?) UI if you resize your game window too small.
I get this error in my game when testing things at different window scales and I also don’t use any UISizeConstraints.
@CriticalGorilla we will investigate soon, given this thread has not been looked at in a while we would like to know if the issue is still reproducible/relevant by you?
Closing out thread due to lack of response. If this issue is still occuring feel free to file a new ticket. Thank you.
