Yes, still relevant.
The fonts in the shutdown overlay and in discover look crappy as well (like in
my screenshots).

In addition I should mention that the mouse interactions (cursor and clicks,
selections) behave as if the email text were in its correct position. So just
the "drawing" is wrong.

I already have QT_SCREEN_SCALE_FACTORS set.
Besides, setting QT_SCALE_FACTOR=2 in addition just scales the user interface
again. The original problem is there nonetheless.

Setting "Scale Display" in the "Display Configuration" to 1.8 results in poor
font qualities. This is in general not reproducable and seems to be random.
An exception is the "Desktop Effects" section in "systemsettings", where the
poor font is always there, see the soon to be attached screenshot.

Reproducible: Always

Steps to Reproduce:
1. set "Scale Display" factor to 1.8
2. go to "Desktop Effects" section in "systemsettings"
3. look at the font of the effect titles

Actual Results:  
poor font quality

Expected Results:  
super sharp fonts

--- Comment #2 from Lukas Schneiderbauer  ---
Okay, I see the problem now.

In 5.6. I had to set QT_AUTO_SCREEN_SCALE_FACTOR=1 in /etc/profile.d since the
plasma-internal scaling options did not work any more (coming from 5.5).

It seems plasma overrides this option now and relies again on the scaling
options one can set in systemsettings. So it works again.

Sorry for the noise.

Since the upgrade to plasma 5.7.2 (from 5.6.5) all icons in qt (4 and 5)
applications are too small on my hidpi-screen.
For things belonging directly to plasma (for example the desktop context menu)
this was also the case for plasma 5.6.
But with plasma 5.7.2 the icons of all qt(4,5) applications like dolphin,
okular, yakuake, spectacle are too small as well. It seems that the
hidpi-scaling only works for fonts and not for icons any more.

Note, changing qt's scaling only seem to influence the font size, but not icon
sizes.

I will attach a screenshot.

Reproducible: Always

[Lukas Schneiderbauer via KDE Bugzilla]

https://bugs.kde.org/show_bug.cgi?id=359962

Bug ID: 359962
   Summary: [wish] linear interpolation in Plotter (QtQuick item)
   Product: frameworks-kdeclarative
   Version: unspecified
  Platform: Other
OS: Linux
Status: UNCONFIRMED
  Severity: wishlist
  Priority: NOR
 Component: general
  Assignee: notm...@gmail.com
  Reporter: lukas.schneiderba...@gmail.com
CC: kdelibs-b...@kde.org

The QtQuick item 'Plotter' (as for example used in the plasma-nm plasmoid)
always uses catmull-rom interpolation on any data it gets. This might not
always be the desired way of plotting the given data. Also, it can lead to poor
artefacts (for example on big steps of the y-values).
To remedy this, I suggest to add an option to choose linear interpolation
instead of Catmull-Rom interpolation.

The soon to be attached patch implements this by adding a Q_PROPERTY
"interpolation" to the Plotter-class, which allows the options
Interpolation.Linear and Interpolation.CatmullRom. The default is still
Interpolation.CatmullRom to avoid changing the behaviour of existing Plasmoids.

Reproducible: Always

[plasma-nm] [Bug 359802] New: weird speed-graph unit labeling

[Lukas Schneiderbauer via KDE Bugzilla]

https://bugs.kde.org/show_bug.cgi?id=359802

Bug ID: 359802
   Summary: weird speed-graph unit labeling
   Product: plasma-nm
   Version: 5.5.4
  Platform: Gentoo Packages
OS: Linux
Status: UNCONFIRMED
  Severity: normal
  Priority: NOR
 Component: applet
  Assignee: jgrul...@redhat.com
  Reporter: lukas.schneiderba...@gmail.com
CC: lu...@kde.org

On the left side of the speed graph in the nm-applet, the units of the graph
are indicated. They obviously are not scaled in a linear way.
Is this intended? I am under the impression, that the graph plots linearly by
default; so for me it doesn't make much sense this way.

The scaling of the labels is reflected in
plasma-nm/applet/contents/ui/ConnectionItem.qml, line 303:
text: KCoreAddons.Format.formatByteSize((plotter.maxValue * 1024) / (index +
1))

in my opinion the line should read
text: KCoreAddons.Format.formatByteSize( (plotter.maxValue * 1024) * (1-
index/5)) )
to get a proper linear scale.

Reproducible: Always

(In reply to Thomas Lübking from comment #25)

No.

> What resolution (logically & physically) are you on (NOT "1024x768", but
> "xdpyinfo | grep  resolution" for the logical and probably
> /var/log/Xorg.0.log for the physical resolution)
$ xdpyinfo | grep  resolution
  resolution:162x161 dots per inch

I'm not sure what you mean by "physical resolution", but my monitor's native
resolution is 3840 x 2160 and it's diagonal length is 27 inch. Assuming my
monitor's physical length ratio is exactly 16:9 (which I didn't check), this
gives a resolution of 163.178 x 163.178 dpi.

I do not have this issue when explicitly setting it to 48p (neither with
decorations nor with the gtk app).

I have the same issue with Plasma 5.5.2 on gentoo with cursor size setting
"resolution dependent".
Are you sure this is a distro issue, given that I use a different distro and
setting the cursor size to fixed "48px" leades to a normal behaviour?
