Android Studio error cursor hover tooltip/suggestion disappears instantly

Question

I have had this issue for a while but just ignored it by viewing Dart Analysis but basically when coding in Android Studio, if I come across a code error, mistake etc. when I hover over the error, usually a tooltip should popup explaining the issue which it does but then it disappears instantly not allowing me to read the issue. If I move my cursor away and over the error it repeats the same process.

I have looked at the error and tooltip settings but nothing fixes the issue. Currently using latest android Studio build. Hovering over tabs, icons etc. allows me to read descriptions, info of said action but not errors.

Does anyone know of a fix apart from trying to reinstall Android Studio? I fear that might be the case.

Thanks.
