Too small window for docstring

Is this webkit? Does it happen all the time? Emacs version? Please also include logs from that particular request.

[Compro-Prasad]

Yes, webkit.

emacs-version: GNU Emacs 27.0.50 (build 14, x86_64-pc-linux-gnu, GTK+ Version 3.24.8) of 2019-04-13

What kind of logs? *Messages* buffer and *ccls* have no special messages.

Window manager is i3 but I get same results on GNOME.

Also, if the docstring is too long, the scroll behaviour is glitchy. After I scroll down, the page scrolls down by 2-3 lines then resets to the first line. The workaround I am using is to select and drag beyond the docstring frame to scroll the docstring.

I'm also seeing similar behaviour.
I'm on GNU Emacs 26.1 on macOS (doom emacs, if it matters)

I do not see "white" window as shown in the first screenshot, I see a black one.
I'm new to lsp-ui (started using it for the first time today) - so I don't know if mine is webkit or not.

@Compro-Prasad How can I check and enable webkit (if it is better)

@mandarvaze Set lsp-ui-doc-use-webkit to t.

I'm seeing similar behavior on 27.0.50. With lsp-ui-doc-use-webkit nil I can consistently reproduce the issue by moving directly from one hoverable point to another; e.g. in CSS mode, if | is point, moving the point from whitespace to |color creates a doc-hover of the correct size for the element. If I then move point directly from |color to |font-size (or any other hoverable css property), the doc string is updated but it looks like the window size isn't recalculated.

I'm also seing this with i3, no webkit.

Edit: I suspect (window-text-pixel-size ...) is giving to little headroom https://github.com/emacs-lsp/lsp-ui/blob/master/lsp-ui-doc.el#L498. Dunno if this is i3 related, tho
