The problem happens on AlmaLinux 8.4. I think it is related to WebKit, but I am unable to upgrade WebKit on the machine because I don't own the machine.

The Hover Hint Window becomes too tiny to see:

It can be resized by dragging, but it will be tiny again next time, so it is still unusable.

It also emits a few errors about "Maximum call stack size exceeded" on getting marginTop, marginBottom, scrollWidth, and scrollHeight. This is one of them.

Which desktop do you use with AlmaLinux? GNOME?

Please check if this discussion is helpful. Since it seems to be a webkit problem I would like to close this issue

Yes

The env vars mentioned in the discussion did not work for me. It doesn't seem the same issue.

Although it seems like a WebKit problem, but it could be a misuse of WebKit API in SWT. From the stacktrace, I see it is trying to get some margin values. Maybe SWT expects -1 as default but WebKit returns 0, something like that. Could you take a look at the stacktrace? I really cannot use LSP editor if this issue persists.
