Looks like this removes the padding from the config page itself, which is the most noticeable due to the ugly header positioning:

Added context

I've been using nested rootston inside KWin and noticed problems with content refresh when using touchscreen. It worked better with mouse. After debugging, it turned out that:

Just a mockup but is this middle ground solution good enough?

To anyone playing with those paddings: please note, that until T8177 is fixed, on X11 with hidpi screens you need to run Plasma with PLASMA_USE_QT_SCALING=1 env variable, as otherwise the font sizes are disproportionate to other UI elements.

Don't do that on X, it causes all kinds of problems.

@pragun Scaling factor of course. Keep in mind you have to log out and log back in for change to take full effect.

I've checked on my PC with the same screen and 5.15.2. It works fine with 2x factor (except the Magic Lamp, which I already mentioned in my last comment - haven't filled a bug yet, will do so soon), but shows similar symptoms when using fractional factors.

OK then, updated!

Well, you could get coordinates of the top-left corner of the placement area for the client, though I personally think it would be better to place the client. If I recall correctly, we do something like that on X11 when maximize restore geometry is not valid.

Any idea what to use instead of QPoint(0, 0) to fix that? (I'm new to this codebase). It's already way better than current behavior, but yeah, won't hurt to make it even better ;)

Small glitch I noticed: when using PLASMA_USE_QT_SCALING=1 on X11 and minimizing window with a KWin effect, Plasma reports unscaled iconGeometry (in logical coordinates instead of real pixels, like 200x850 instead of 400x1700 on 2x screen), resulting in wrong animations. This doesn't happen on Wayland.

Nope.

Good points. Guess I got overly excited that I finally figured out the test infra :D Updated; also removed the unused sizeChangeRequestedSpy.

Added a test case.

ping :)

Well, only if you consider blur to be a property of console itself, not the whole terminal window.

Turns out the scrollbar now got changed indeed and is going to be configurable in 5.13, including extra slim option like the one this implements. So, I'm reopening this now, although it sure will need some adjustments.

Although I really like smaller scrollbars and will keep them in my gtkrc, it turns out it's not really intended in Qt - my session had DPI adjusted only by font setting, the screen scaling factor was still 1. After adjusting the screen scaling factor, the scrollbars became fatter :( So, closing it.

Oh, so it's a bug? I hope it doesn't get fixed then, as the tiny scrollbars look way better :D

There you are :) Firefox, System Settings and gedit, before and after.
