There is a big problem with your CPU Gen and they are melting down, if the damage is done already you will need to send it to guaranty >_ <
Really hoping it's not a CPU issue :') This issue is only affecting Live2D and no other programs. Video games run fine, so I'm crossing my fingers. ><
Thank you for using our product.
Please answer the following two questions regarding this issue:
1. Are there any resident software programs? (Mouse settings, antivirus software, etc.)
2. Does the same problem occur with Cubism 5.2?
You can download Cubism 5.2 here:

Thank you in advance.
1. I have Logitech GHUB
2. Two days ago, when it wasn't working, 5.2 did not work. Today both 5.2 and 5.3 works fine
Thank you for trying to help. I'm not sure what fixed the issue but it's acting completely normal now. I'll keep monitoring to see if something comes up again
Thank you for reporting your issue.
Please let us know if you experience any further problems.
