Created attachment 140963 [details] A screenshot of "Detailed Memory Information" window After right clicking on a process to view its "Detailed Memory Information" the new window that is created contains what appears to be some sort of web view showing unstyled HTML with the memory information. I don't know why this page is a web view in the first place. It seems out of place in KDE.
ksysguard is no longer maintained, in Plasma 6 there is the Plasma system monitor for this task. If your issue still happens with the Plasma 6 replacement, please re-open and we can move this bug to the new product, thanks!
