--- Comment #3 from Evert Vorster <evors...@protonmail.com> ---
I made a small mistake in the bug report, stating that the version of Plasma
was 6.2.4. The version of Plasma is actually 6.3.2, and of course this bug is
present there too. This was plainly evident in the extra information that I
included in the initial bug report.
Actually, anyone that actually read the bug report with the intention of
helping would realize that this bug is trivially replicated on any panel with a
native resolution of 2560x1440.
I looked through the bug database for something similar, or even close, and
nothing showed up. With no bug reports, there is a very low likelihood that
there will be any changes in later versions of the same product.
However, here is how to test for this bug locally:
1. On a display panel that has a native resolution of 2560x1440, enable that
native resolution in display properties.
2. In a terminal, run "xrandr" <- This produces a list of resolutions the
monitor supports, with the active resolution marked with a "+"
You can confirm that the active resolution of the screen equals its native
resolution.
3. In Display properties, adjust scaling of this monitor to 130% <- This
display now outputs 1969x1108 as it's active resolution.
4. In Display properties, adjust scaling of this monitor to 135% <- This
display now outputs 1896x1067 as it's active resolution.
As you can plainly see, there is no scaling option on this panel that outputs a
resolution of 1920x1080 on xrandr.
So, scaling absolutely positively does do that, mr. "not a bug"
I would like to use the higher native resolution of this built-in panel to
avoid screen artifacts when I use the computer normally. Obviously I use my
laptop for more than just gaming and screen recording, and then scaling on the
native resolution of the monitor makes quite a huge difference, and is the
preferred choice.
However, the fullscreen resolution reported by xrandr is the resolution used by
my screen recording software, as well as all the games that run in fullscreen
mode. I would like the fullscreen resolution reported in xrandr to be 1920x1080
so that the footage captured from this scaled monitor does not get scaled again
in the video editor. Currently there is no way to position the scaling slider
to get this fullscreen resolution, as I calculate that to be 133.3333333333%,
and the slider only goes in 5% increments.
It also does not accept it if I type in this percentage, rounding it down to
132.5%
At the moment I have actually set the monitor to the lower resolution as a
workaround, but this is not ideal as there are artifacts on the screen when
viewed at this resolution, because it is not the native resolution, and LCD
panels scale between non-native resolutions quite poorly.
Which was the whole reason for inventing scaling in the first place.
