@rogerwang Could you take a look at this please?

[UtterDonkey]

Might I suggest you rename this issue so that it's more obvious it's an issue with frameless windows themselves and not with the frameless examples?

[UtterDonkey]

I'm not able to reproduce this problem in v0.82.0.

[UtterDonkey]

I think this may have something to do with it: nw82...nw83#diff-52fe046e03b7bd92f94816d435f9ed44082d363c02741801391d796e720d2765

thank for clarification.

[rogerwang]

I was testing my local fix with OP's sample, which uses -webkit-app-region: drag.

[UtterDonkey]

Have you managed to fix any other of the issues with frameless windows like transparency, rounded corners etc.?

work for me thank for your time

[UtterDonkey]

I will test it for my issues on windows as soon as possible and get back to you.

@rogerwang

I get this weird effect after moving a window with resizable: false and then if I make it frameless, it removes the rounded corners.

@rogerwang

I get this weird effect on the borders after moving a window with resizable: false and then if I make it frameless, it removes the rounded corners.

-webkit-drag-region CSS property and titlebar issues is fixed on Ubuntu 23.10 x86_64.

However there're still some problems about transparency. It would be a sync issue about Gnome' window manager. (Also it can be reproducible in XWayland and Wayland).

Also still context menu of draggable area is still showing "(empty)" text instead of opening system menu (like Windows does).
