I see you removed --notransparency for KDE 4.9. I relied on that flag because of broken NVIDIA drivers. Transparency works alright here, so Konsole enables it. But when I switch desktops and then switch back to the one where Konsole is open, the GPU hangs for several seconds. It's that bad that I can almost fetch a coffee in that time. Disabling transparency has been the recommended workaround for NVIDIA users that suffered from this. Reproducible: Always
Created attachment 73248 [details] part 1 to the fix
Created attachment 73249 [details] part 2 documents the need for the flag
