SUMMARY In Kubuntu 20.04 or Neon 18.04: when you scale the screen for example to 125%, all windows get a bold black border (window decoration / aurorae) even if no window border was set. STEPS TO REPRODUCE 1. Go to the settings and set the display scaling to 125 % 2. All windows get a bold black frame - even if you set "nor borders". 3. You can test it with the window decoration (aurorare) "Qogir". OBSERVED RESULT s. above. EXPECTED RESULT Windowd do not change by scaling the screen. No border frame. SOFTWARE/OS VERSIONS Linux/KDE Plasma: neon 18.04 and Kubuntu 20.04 (available in About System) KDE Plasma Version: 5.18.x KDE Frameworks Version: ? Qt Version: ? ADDITIONAL INFORMATION
Meanwhile after some minor updates I confirm the problem: a) Boot without power supply => black screen even before login dialog b) Boot with power supply and then after login working normally, then after a standby => black screen. I am using Kubutu 20.04. on Thinkpad T495 (AMD Ryzen 3500U CPU with Vega mobile Graphics).
Sorry: my last comment concerning the "black screen" problem was wrong here. It belongs to another bug. You can delete it here. But the scaling problem still exist.
You changed the summary so that the problem hapens only when "quogir" aurorare windows decoration is used. This is NOT correct. The scaling problem happens to many other decorations too like: "McMojave-light", "WhiteSur", "Artim-Dark", "Arc Dark", "Arc" and many more. Only "Breeze" works as expected.
It was just meant to be an example, not an implication that it happens with only that theme.
ok, i understand, but then it was a bit misleading. Any chance to fix it soon? It is quite important on typial 14 inch screens with smaller screens with high (Full HD) resolutions.
>1. Go to the settings and set the display scaling to 125 % X or wayland?
kubutu standard = X.
