Kubuntu large icon task switcher #7917
Comments
Looks like your icon theme has icons for all apps on the screenshot except Telegram |
I think this link would be very helpful https://bugs.kde.org/show_bug.cgi?id=351055 It can be fixed by the application itself. |
Please, TL;DR, what is needed? |
An app should provide correct/good icon to kwin. Please, read comments 34-35 |
tdesktop provides 256px icon. Is this good/correct? |
Unfortunately, I don't know :( |
I've found more information about the bug. https://www.reddit.com/r/kde/comments/9kz6gv/please_make_kwin_automatically_recognise_correct/ TL;DR:

tdesktop installs icon to ~/.local/share/icons |
Okay, it seems, I've found the right answer.
You can inspect the properties of other application windows by using the |
It is set, otherwise there wouldn't be any icon |
|
Yes, but there is only one 48x48 icon. Firefox has six icons. |
As you can see, 256px icon is set. If Qt resizes it, tdesktop can't do anything with that.

I googled more and what I found out. |
But he just added a 128px png, tdesktop already sets 256px png. |
Ok. I give up. I hope there would be someone more opinionated in Qt than me, who digs deeper into Cantana's master branch and find the workaround. Let's leave this issue open. |
I did some testing. 128x128px icon appears in xprop only with KDE platfromtheme plugin, that can't be used with binary from github. Sorry. |
@Aokromes can you close this as 3rd party bug? |
Well, I tried to patch Qt and icon is 48x48 anyway |
Icon is OK on snap |
Well, I found the root of the problem. It is /usr/share/icons/breeze/apps/48/telegram.svg. KDE developers for some reason provide telegram icon in breeze with 48px size only that overrides telegram's 256px icon. Probably, you should open a bug in KDE bugtracker. |
Thank you so much! |
