Okay, so best way to describe this is the following: When I load up Vanilla every so often I sometimes can click the buttons and other times I can't whatsoever. I have brought this issue up in the Technic Discord and I was helped but it doesn't seem to work anymore. I was told to turn on the Touchscreen Mode to fix the issue but it doesn't fix it. I'm on 1.12.2 and haven't had issues like this before a month ago roughly. Honestly. I don't know what to do to fix the issue...
