How are you setting the scale below 100% in the Display Configuration KCM? The minimum value is 100%. Also can you please attach a screenshot that shows the problem? Created attachment 136888 [details]

Nate, Why do you think i would make a fake bug report ? Do you really think I have some reason to lie to bugs.kde.org ? Why would i presume the idea of the display scale going below 100% and also then presume there must be a bug for UI elements in the title bar of any window try to display on such a screen ? I can assure you i make *thorough* tests before submitting any bugs to bugs.kde.org as well as first checking to see if there are already any bugs already submitted with the same of similar aspects As a secondary note - although this really should be sibmitted as a separate but *related* bug (unless it already has been) Settings the/a Screen Scale to below 100% also gives at least an X coordinate offset issue - in other words a mis-alignment of UI Elements like things one is meant to be able to click on, like say a browser TAB, a menu item etc etc with respect to the actual mouse pointer x/y position Example Setup: 32" Widescreen Monitor Monitor set to 75% Scale via KDE System Settings > Display Configuration In my seamonkey browser for example, I had serious issue's with the correct TAB being selected via the left mouse button Upon Pressing the left mousse button while the moues pointer was on top of a browser TAB a tab 4 tabs down instead got selected. This ONLY happened when the screen/monitor seamonkey was on had it scale set to below 100% Note 1:
This big report was originally made when i was using a SONY 40" monitor
I have subsequently switched over to a SONY 32" monitor
the 40" monitor was just far far too big me me as a normal desktop monitor
and i also had decided to change the monitors display to a smaller and more prefered scale size when i first saw this bug.
NOTE 2: My original references to DPI may have been somewhat mis-leading
as i did infact mean "Scale"
Oh hey, I never noticed that it was possible to set the scale factor as low as 50% on Wayland, my mistake. I was not accusing you of anything; no need to feel defensive. :) Unfortunately with a 4k screen, I cannot really test, as going from 200% scale to 50% scale will make the system unusable. Thank you for recognising KDE's scale ability :) *** This bug has been marked as a duplicate of bug 432766 *** |
KDE Plasma Wayland - Monitor DPI Below 100% Effects Window Title Bar Display: DESC: Window Titlebar UI buttons stop correctly displaying on the top right-hand side corners with DPI settings below 100% NOTE: Issue only shows up on screen/monitor who's DPI setting falls below 100% DPI settings at 100% and higher do not cause any issues Graphics Affected: Window Titlebar Minimise, Maximise, Close - UI Button's DE's Bug Appears In: Plasma X11: N/A Plama (Wayland) Xwayland: YES Plasma (Full Wayland): YES REPRODUCIBLE: YES 1. Settings > Display 2. Choose a/the screen/monitor to have a DPI lower then 100% 3. Set a value lower than 100% for the DPI 4. Press Apply 5. Open an app up, example KATE EXPECTED BEHAVIOUR: To see all the windows and all their respective related UI stuff change in a scale proportional to the stated DPI WHAT DOES HAPPEN: Any/All windows open will have the above stated UI buttons hidden from view in their titlebar NOTE: The Window Title bar options will become visible if the mouse pointer is moved over them NOTE 2: If you have at least 2 monitors, and at least one of them has either not had its DPI changed from the default OR has a DPI Greater than 100%, then moving the window that has the hidden UI elements over to the screen/monitor that has a DPI or 100% or greater DPI, one will immediate see the windows titlebar elements again Also vice-versa, moving the same window back to the/a screen/monitor who's DPI is set to below 100%, once again the windows titlebar UI elements will again become invisible. NOTE: Changing any of the below also had no effect, with the exception that changing 'Window Decorations' from Breeze to Plastik meant that NO UI elements at all were displayed in a windows titlebar (the ones on the left-hand side) until a re-boot was performed.
