Created attachment 107888 [details] a firefox process on top of the list Firefox processes are launched with a bunch of garbage in their arguments. I have the Command column enabled and when one of such firefox processes is on top of the list the height of all rows in the table changes in response to, I presume, line breaks in the command string, even if they are not displayed. Another possible reason is that some of the characters in that string are rendered with a font that has different line height. But no matter what the real reason is I think such behavior is unwanted and should be considered as a bug, i.e. the row height shouldn't change to fit in the invisible text.

I cannot reproduce this (also using firefox) on v 5.15. Does this still happen to you?
(In reply to Richard Llom from comment #2) > I cannot reproduce this (also using firefox) on v 5.15. > > Does this still happen to you? Although this does not seem to happen with current Firefox anymore, it still can be reproduced with Firefox v55. Here is a cmdline dump for convenience. To reproduce, for example: $ kwrite `cat firefox-cmdline`

Confirmed
ksysguard is no longer maintained, in Plasma 6 there is the Plasma system monitor for this task.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!
