Created attachment 153170 [details] A screenshot where you can see in "Hot Corners", that there are no buttons. SUMMARY *** NOTE: If you are reporting a crash, please try to attach a backtrace with debug symbols. See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports *** STEPS TO REPRODUCE 1. In 5.26 open > sytemsettings > workspace behavior > hot corners . 2. 3. OBSERVED RESULT No buttons on the edge and on the side of the screen image. For users who use touchscreens also no buttons can be found. EXPECTED RESULT Buttons for creating hot corners should again be visible or simply displayed, so that an action can be choosed for a hot corner. SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: (available in About System) KDE Plasma Version: KDE Frameworks Version: Qt Version: ADDITIONAL INFORMATION
As an important info: In EndeavourOS KDE this bug is not present, the buttons are visible in Plasma Version 5.26. I detected this bug only in Arch Linux KDE and Manjaro KDE. Perhaps it exists also in other distros with KDE.
It looks like you're using a Kvantum theme. Does the issue reproduce with the Breeze Application style?
(In reply to Nate Graham from comment #2) > It looks like you're using a Kvantum theme. Does the issue reproduce with > the Breeze Application style? I never used a kwantum theme so far. But I made the test with the Breeze Global Theme. I was really surprised, after applying the Breeze Theme, that the buttons reappeared in Hot Corners in Workspace Behavior and the menus, clicking on a button, opened up again. A few days ago an idea came into my mind, that a theme could be the cause for this issue. And I was confirmed now. But what theme ? In my MacOs-Layout I use Monterey Kde Dark Theme, WhiteSur Dark for the icons and McSur Dark for Plasma Style. So, I reapplied Monterey Dark and the exact themes and icons configuration that I use for my system. I wanted to apply for each category the themes,switching themes one by one, to see what theme is responsible for the non displaying of the buttons. And quickly I found the solution: It's McSur Dark Theme ( I use it in Plasma Style), that is the cause for this issue. When I switched the themes, using Monterey Dark instead of McSur Dark for Plasma Style, the buttons in Hot Corners were again visible. One year ago, I used McSur Dark to get my blurred panel more dark. Monterey was lighter. But after a recent update, Monterey Theme got darker in the same way as McSur Dark. In the future I'll use Monterey Dark in Plasma Style instead of McSur Dark. But anyway, there must be an issue in McSur Theme. One year ago, when I first used McSur there was no problem with the buttons in Hot Corners. And a few weeks ago, when McSur got updated, this issue arised.
Sounds like it!
