Description Swâmi Petaramesh 2022-10-26 15:36:40 UTC
SUMMARY

Hot corner (upper left) that displays a preview of all open windows view worked perfectly in Plasma 5.25, doesn't work anymore in Plasma 5.26 in an X11 session, still OK in a Plasma Wayland session.

Putting the mouse cursor in the upper left corner does cause the corner to turn blue, but nothing else happens.

Going into system settings, screen borders, and changing anything about the corners make it work ONCE and only ONCE.

Everytime settings are changed, the corner will work only ONE time.

Looks like a perfectly reproductible regression/bug...

Can you try again with Plasma 5.26.2 (released yesterday) and see if it's better now? A fix in there might have affected this.
Comment 2 Swâmi Petaramesh 2022-11-09 07:32:45 UTC
Hello,

Plasmashell 5.26.2 didn't solve the issue.
Comment 3 Swâmi Petaramesh 2022-11-24 09:07:50 UTC
Plasmashell 5.26.3 didn't solve the issue either.
Comment 4 Nate Graham 2022-11-28 22:22:27 UTC
Can you open Present Windows using the Ctrl+F10 keyboard shortcut? Or is that broken too?
Comment 5 Nate Graham 2022-11-29 17:44:22 UTC
.
Comment 6 Swâmi Petaramesh 2022-11-30 19:37:01 UTC
Yes, [CTRL]-F10 does indeed work (thanks for the shortcut I didn't know, it will help) but the hot corner does not, although it turns blue showing that “something should happen”.

It works only ONCE after configuring it to “no action” then back to “Show windows on all desktops”, then no more until playng with config again.

Event at session startup, it does not work.
Comment 7 Nate Graham 2022-12-01 20:45:07 UTC
Is the hotcorner broken for everything? Or just when assigned to the Present Windows effect?

Are all corners affected, or just the one you're trying?
Comment 8 Swâmi Petaramesh 2022-12-02 09:20:22 UTC
Hello,

The upper left corner is broken with described behaviour, for any action you asssociate with it.

But per your question I just tested and all the other 3 corners work good, as expected.

That's a bit of a mystery...
Comment 9 Vlad Zahorodnii 2023-01-23 14:04:30 UTC
Can you share your screen layout settings please?
Comment 10 Swâmi Petaramesh 2023-01-23 14:09:51 UTC
Hello,

Could you please be more specific about what exact information you would like (“screen layout” can mean a lot...) or if you would like screenshots of specific parts of my KDE settings ?

TIA.
Comment 11 Nate Graham 2023-01-23 17:30:12 UTC
Screen layout, as in the arrangement of your screens in System Settings' Display Configuration page.

Here you go !
Comment 13 Nate Graham 2023-01-27 21:04:33 UTC
With only one screen just like you, it's working for me on X11 with current git master FWIW. Could you try again with the Plasma 5.27 beta, or the final release of Plasma 5.27 in a few weeks?
