SUMMARY Bear with me, as this is my first ever bug report; When I open a new konsole instance or resize an existing konsole window (there might be a few other things) there is no blur. I can get blur to work again by right clicking, going to "Switch profile" and choosing "default profile" (which is also the only option). Blur seems to be working as it should everywhere else (Plasma desktop, Qt5/4 applications) except Yakuake (I think that's a separate already known bug, though). On OpenSUSE Tumbleweed using packages from KDE:Extra repository STEPS TO REPRODUCE 1. open window or 2. resize window OBSERVED RESULT No blur until I "switch profile" to my only profile (default) EXPECTED RESULT blurred terminal background SOFTWARE/OS VERSIONS Linux/KDE Plasma: 4.19.5-1-default (available in About System) KDE Plasma Version: 5.14.4 KDE Frameworks Version: 5.52.0 Qt Version: 5.11.2 ADDITIONAL INFORMATION 64 bit intel CPU; integrated intel HD graphics; 2010 Thinkpad T410; openSUSE Tumbleweed; Konsole version 18.08.3
Further investigation demonstrated that this bug is not a konsole bug but a QtCurve bug. Steps to reproduce therefore must include: 1. choose QtCurve as widget style 2. edit QtCurve theme to have transparency 3. make sure konsole theme has transparency and blur 4. go to settings > switch profile > default profile to reset blur 5. open konsole, resize konsole, or open a new tab in konsole. Test multiple by repeating step 4 expected result: konsole will have blur and/or remain blurry even after resizing / opening a new window / opening a new tab
I can confirm. open konsole right click, select "Edit current profile..." select "Apearance" tab, click "Edit..." button Adjust "Background transparency" level apply the settings close konsole open system settings > application style > widget style select QtCurve style, click "Configure" button select "Opacity" section, adjust transparency level of windows apply the settings open system settings > desktop behavior > desktop effects search for "blur" effect, enable it, click the button to configure it ajust "Blur strength" and "Noise strength" apply the settings open konsole Result: konsole window is transparent, there is no blur effect right click, "Switch profile", select "Default profile" (or the profile previously edited/configured) Result: now konsole has blur effect resize konsole or press ctrl+shift+t to open a new tab: blur effect disappears and konsole becomes transparent again Operating System: Arch Linux KDE Plasma Version: 5.15.1 KDE Frameworks Version: 5.55.0 Qt Version: 5.12.1
