Problem
We have a RHEL x64 machine with KDE Plasma 5+ and we don't want any fancy graphics or effects. We tried manually disabling the effects through the settings menu, but this has had little effect on removing options which cannot be adjusted. For example, there are some menu transparency effects which remain even when disabled in the settings.
Question
How do we fully disable all effects and make Plasma as lean and light as possible?
Desired Outcome
A plasma workspace without any graphical effects.
KDE/LXDE
The obvious long-workaround/alternative would be to install and use LXDE instead of Plasma. Prior to going to this option, we would like to determine if the desired outcome can be achieved within Plasma itself.
Research
A similar problem in version 4.9 [1]:
In KDE 4.9 one can disable the transparency of most items, but not of the Plasma Panel. However, that thing annoys me to all extent. I cannot have applications full-screened then Alt-Tab to another window as the full-screen application bleeds through the panel and I can no longer make out what is actually in the panel (such as reading the clock). Is there any file that transparency depends on that I can simply rm away?
