Same thing after these commands:

Does the size look better if you set PLASMA_USE_QT_SCALING=1 and restart
plasma?

This should definitely be fixed now with code overhauls to how the tab box code

Yeah, I hear you.

Thing is, if people never see the broken Firefox icon, they won't be able to
help fix it. Ever since I've seen it, it's been so annoying that I've been
working to get it fixed:

https://bugzilla.mozilla.org/show_bug.cgi?id=1371932
https://bugzilla.mozilla.org/show_bug.cgi?id=1371931
https://bugzilla.opensuse.org/show_bug.cgi?id=1057115
https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/1715213
https://bugs.launchpad.net/ubuntu/+source/mozilla-thunderbird/+bug/1715214

It's also not universally broken; openSUSE already patches the icon to not be
ugly, and hopefully my efforts will result in the same for Ubuntu too, or even
all Firefox and Thunderbird users.

So my preference would be to fix the DPI issue originally reported here, which
will fix the size problem for hiDPI users and result in *most* icons in the
Large Icons task switcher being nice and sharp, and also bring greater
visibility to the few remaining icon problems so that people can help get them
fixed.

But you're the maintainer, and we'll respect your decision.

--- Comment #16 from Martin Flöser  ---
@Nate: I fully understand that the problem is already present today. I only
point out that the issue is more exposed if we support it. We have been at
showing smaller icons (users were vivid about it), we have been at showing
pixelate icons (users were even more angry about it).

The problem is that the users don't understand that Firefox provides a bad
icon. What they see is that it looks either bad by having partially large icons
and small icons or that it's pixelated. This gives Plasma a bad look and many
users get really, really angry about it and rant about the missing finishing
touch on social media. I'm writing this because we have been there, we
experienced these issues especially about the upscaled icons in large task
switcher. You might be able to live with it, but users with OCD cannot.

I don't have a problem with changing the small one to support high dpi. For the
large one I'm unsure, because I see lots of other issues coming in for us. I
could say "I don't care, just support high dpi", but that would mean ignoring
almost a decade of experience on Alt+Tab and it's issues ;-)

Hmm, I don't seem to be making myself understood very well.

Martin, right now, with a non-hi-dpi screen (that is to say, most of them), the
problem you are trying to avoid is already present: programs that don't
correctly specify high-res icons show ugly pixellated icons in the Large Icons
task switcher. That's how it is right now. I live with it myself.

If we make the Small/Large Icons task switcher respect the system DPI properly,
we aren't losing anything. On the contrary, we're making making them work,
because right now they're *unusable* for everybody with a hi-dpi screen. I
don't think it makes sense to avoid fixing this clear bug just because making
the broken thing work allows people who use it to experience another,
pre-existing bug that they already know about and live with.

What I mean is that right now the Small Icons one is unusable on a high-dpi
screen. By increasing the size of both (for high-dpi setups) the small one
would be the same as the current big one with mostly sharp icons, while the big
one will have some pixelated icons, but for those who want it, allow faster
navigation through many windows because the larger size makes it just easier.

Couldn't those users simply select the "Small Icons" switcher?

That depends on whom you ask. We have many users who think that's not
acceptable and it's better to have smaller icons then. Both are valid
approaches. It's just something we must keep in mind. Fixing this issue creates
(or exposes) new issues.

We already get bad icons for many windows, though. That's not a regression
introduced by Michael's experiment, it's something we already live with today
for non-hidpi displays. See https://bugs.kde.org/show_bug.cgi?id=351055

So I don't think we lose anything by increasing the size of the icon switchers
on hidpi displays.

Partially probably a CANTFIX. There's probably something we can do as you
showed by hacking the file (thanks for trying!). What I'm slightly worried
about is that we don't get good icons for all windows. Especially Firefox and
Chromium are traditionally candidates for bad icons. I just xproped by Firefox
and it only has 48x48 as max icon and Chromium has exactly one icon in 64x64.
Compared to e.g. Kate which has a range from 16x16 to 128x128.

So upping the small icon switcher shouldn't be a problem. For the large icon
switcher we might end up with an unpleasant experience. And from bug reports I
know that users complain about that :-P

Yes, much better. And the Firefox icon is already blurry without a HiDPI
display, so that isn't a regression.

Created attachment 107687
  --> https://bugs.kde.org/attachment.cgi?id=107687=edit
manually patched big_icons tabbox with iconSize: 256

Attached a screenshot for the manually patched file... I for one think it's
better to have a blurry firefox icon but have all the Qt/KDE provided icons big
and shiny :)

The pixelated icon is Firefox's problem; see
https://bugzilla.mozilla.org/show_bug.cgi?id=1371932. Same for Thunderbird:

to be precise, all the icons I have seen so far perfectly provide larger sizes,
with the only exception I noticed so far being firefox. That one becomes quite
blurry indeed. But at least for the small icons one I guess it should be easily
fixable without suffering from that problem.

Hmm, so maybe there's more we can do here, even if it isn't perfect.

Sounds like this is a WONTFIX for X11, then? Or more like a CANTFIX.
