Mouse disapears on xwidgets

[A6GibKm]

When opening a webpage using xwidget-webkit-browse-url, the mouse disapears when it is above the buffer. It appears once again after it hits the scrollbar, and there are problably other triggers for it to fix itself.

Environment

Fedora Silverblue 33 GNOME 3.38 Wayland

How to reproduce

• Compile emacs with ./configure --with-cairo --with-modules --with-xwidgets --with-pgtk
• $ emacs -Q
• M-x xwidget-webkit-browse-url and enter some url
• Move mouse above buffer

Disclaimer: Due to some issue with my OS I am unable to run Emacs without pgtk, and therefore to test this in a clean setting.

reproduced. thanks for finding this issue. it seems to be a mainloop-related issue, and is very difficult. i'll try to debug.

Try to see if this is reproducible in a non-pgtk emacs build. Sadly I can't test that myself and the flatpak version which I can test is not built with xwidgets.

It is not reproducible on X-build.

it seems to be a mainloop-related issue,

That was misunderstanding.

Try #65.
