Description doncbugs 2022-09-14 01:14:13 UTC

SUMMARY
Desktop Layouts applied through Global Themes no longer seem to be resized to fit the display if it was smaller. In other words, a Panel Layout that was for a screen 1920 pixels wide will not resize to a screen that was 1600 pixels wide (unless plasma is restarted). Instead, the panel will extend off of the screen.

STEPS TO REPRODUCE
0. Have a display that is not the size of the target theme
1. Download a Global Theme (I used Apple-Ventura-Dark)
2. Apply the Desktop Layout
3. 

OBSERVED RESULT
The panel extends off of the right side of the screen. The clock and applets are not visible. Editing the panel also shows no handles to resize the panel (as they are off screen). 

EXPECTED RESULT
The panel refreshes itself and shrinks to fit the screen.

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: KDE neon Unstable Edition (Docker)
KDE Plasma Version: 5.25.80
KDE Frameworks Version: 5.98.0
Qt Version: 5.15.5

Additional Information:
I believe that previously, larger panels would shrink to fit smaller displays, but smaller panels would not expand to fill say, a 2k display. Simulating this with the Docker image is fairly easy by creating a second display that's smaller than the specified themes (usually meant for 1920x1080).

Do you remember the last time this worked? Was it working in the released 5.25 version?

Comment 2 doncbugs 2022-09-16 00:31:54 UTC

I have not quite been following things that closely, but I want to say it worked in 5.25(.1?). I had a 5.25.3 iso and confirmed that the bug is present there.

If I really think about it though, the reverse problem has been true for a while: A desktop layout with a short panel would not automatically maximize to a wider desktop, even if the exported theme may have had a maximized panel. In that case, it would have to be manually resized/set to maximize panel. I think the only thing that must have changed is that the panels no longer get updated when applying the theme.

Thank you for the bug report. Unfortunately we were not able to get to it yet. Can we ask you to please check if this is still an issue with either Plasma 5.27.11 (the current LTS version) or Plasma 6.2.5 (the latest released version)?

If you can still reproduce the bug, please change the Status to "CONFIRMED". Thanks.
