I have seen this issue but it quite a few months ago. I don’t get it on my 7.11.3.
You can try upgrading, but I fear there might be something else breaking your screen.
I wonder if you have customizations? If you are overriding some file in custom, the one that was fixed to solve this issue, then you don’t get the fix. If this is the case, then you were warned about such files during your last upgrade.
I will upgrade to the latest and see if it fixes it. I have to upgrade my php first it seems. Let me try that and I’ll let people know if it resolves it or not.
