Hi @zs01 ,
Is it the same behaviour as that captured by another user here?
I’ve watched your screen capture several times, but I’m still having difficulty trying to describe/articulate the specific undesired behaviour that is occurring.
When you say the cursor becomes ‘misaligned’, is it moving itself forwards or backwards a character, or is it like you have pressed the Insert key, or is it ‘auto selecting’ a text block, or something else?
I’ve added some troubleshooting ideas to the linked post, but it seems you have already thought of them (extension conflicts etc).
