Ohhh now it happens with Vray, so its very random.
All I simply do is
-Open Lister (turn off/on doesnt matter at all)
-Close Lister
-Reopen lister
-Now the window has issues
-Use buttons
-Crash
Maybe my scene has an issue, this didnt happen before.
I attach a sample from a Corona file and a Vray File.
I cannot attach the scene its too large, so heres a
link from Drive.
Hope this helps.
