Description PK 2025-06-19 07:56:59 UTC
SUMMARY
Since plasma 6.4 bug since plasma 6.4  bug 499833 is back. That means that my autohiding top panel doesn't allways show up when I call it. And that I have to enter edit-mode to make that possible again.

STEPS TO REPRODUCE
1. create autohiding panel
2. start plasma 6
3. bump to rim of the screen to call the hided panel

OBSERVED RESULT
quite often nothing happens

EXPECTED RESULT
panel shows

ADDITIONAL INFORMATION
Comment 1 PK 2025-06-20 06:01:53 UTC
I'm testing again... It seems this only happens when I start LibreOffice (28.08 beta 1) as first application after startup.
So imho this is not important.

But when I learn other things about this behavior I'll inform you.
Thanks.

After some testing  I can be more specific now.
This bug feels a lot like bug https://bugs.kde.org/show_bug.cgi?id=499833 ( Bottom panel of plasma 6.3 appears nicely at startup but auto hiding top one still doesn't. February 2025).
But when I look closer there is a difference.

After plasma is completely started, I can successfully "call" the (auto)hidden top panel by bumping the cursor against the top of the screen BUT
when plasma is completely started AND I start a program that wants to use the global panel immediately after, THEN the top panel won't show. In that case I have to enter edit mode first.

I have the same issue, just after the startup my bottom panel with auto-hide on (OLED screen) is not showing, I enter edit-mode and back and it starts to work normally.

Comment 4 PK 2025-07-21 09:33:44 UTC
After working quite some time with plasma 6.4, I conclude that in far more than half of the times after startup the top panel only shows after going in "edit mode". 
It feels like a regression into bug 499833

Can you share a screen shot of the entire auto-hiding panel, so I can see which widgets are in it?
Also, can you share a screenshot of the panel settings for it?

Thanks.

I'm really sorry TraceyC, I missed your kind reply.
Here is the screenshot you wanted to see.
And even just before I started to write this, I had to enter "edit mode" to get the top panel ready to show.
Thank you

I was able to reproduce this on Plasma built with git-master with a similar panel setup, but only after waking the laptop from sleep
The top auto-hiding panel, set up the same way as in the screenshot, would not unhide. I didn't see the blue highlight indicating the mouse is near the unhide area. I had to enter Edit Mode to get it to unhide.

Thank you so much for looking in to it. Great that you could reproduce.
