This tells me your theme is not compatible with plasma 6 or is otherwise incomplete.
Please switch your desktop theme.
Breeze as the control.
Extra explanation:
Those settings correspond to “Opaque”, “Solid” and “Translucent” folders in the plasma desktop theme directory. I just checked and Breath does not have these directories. So it will not function correctly with those plasma panel settings.
For some further styles besides the default that I know works with plasma 6 see all the Mace things:
Switching to the Breeze theme does indeed allow me to switch the setting persistently. However it seems that with that I can reproduce the instance where the panel appears pitch black and somewhat pixilated, if I operate an application in full screen and have the panel’s opacity set to “Translucent”:
Is it specifically on wayland? Or does not matter?
Hidpi? Using a display scale factor like 1.25x ?
I had a similar error that presented a little differently. But may be of interest to you.
Here is my applied workaround with commented reference; /etc/environment
# qt wayland font bug https://bugs.kde.org/show_bug.cgi?id=479891
QT_SCALE_FACTOR_ROUNDING_POLICY="RoundPreferFloor"
In case that in any way related to some of the other variables here are the other QT ones I have
# QT wayland
QT_QPA_PLATFORM="wayland;xcb"
# Less Debug Logging
QT_LOGGING_RULES="*.debug=false"
# Some hidpi stuff for QT
QT_AUTO_SCREEN_SCALE_FACTOR=1
QT_ENABLE_HIGHDPI_SCALING=1
It indeed happens on Wayland, haven’t tested X11 yet. But I am indeed using a 1.5x display scale factor (and 1.75x on my second screen).
Edit: Ok after a restart using the Breeze theme as recommended works, all panel modes seem to work as intended.
Maybe, however it looks better or to be a bit more objective, Breeze is also incomplete for Plasma 6, take a look at the icon pack applied in Dolphin for instance:
The Iconpack used in Breath looks plain consistent, the one I get with Breeze looks like a bug to be honest.
Fortunately I can use the Breeze Theme and apply the Breath icon pack(and accent colour) to it, but still, I assume this will get fixed soon, but if not I am going to report it as well.
Thanks a lot, that’s all I am asking for. I just want to report all issues I have on Manjaro, in order to make this distro and Linux as a whole better.
And since this is a fresh install most issues I am facing should be issues everyone could be facing after their first Manjaro install.
I also only have “Breeze”-icons and “Breeze dark”-icons, with “Breeze”-icons it works(the “Breath Dark”-theme is using that one) with the “Breeze Dark”-icons which the “Breeze Dark”-theme is using it doesn’t look as good.
You can either switch the icon pack directly or click on a theme and go to more options and than only check the box to apply the icon pack of e.g. the “Breeze Dark” theme.
TLDR: The Breeze Dark icons are the ones at fault, the Breeze theme uses the Breeze Dark icon pack, while the Breath Dark theme uses the Breeze icon pack.
It’s the opposite, it’s Breath who is not following Breeze standard. In Breeze, the standard is: small icons like 16px and 22px should appear monochrome, because it’s easier for eyes to differentiate the details with small monochrome icons.
Thanks for the reply,
however I have 4 icon packs installed “Adwaita”, “Breeze”, Breeze Dark and “HighContrast”.
Breath Dark seems to utilize the “Breeze” icons, while Breeze Dark seems to utilize Breeze Dark icons.
Both have a scale of 22x22. I did not change any of that.
And this is how they look in Dolphin for me:
As you can clearly see ‘Breeze’ does it “right” while ‘Breeze Dark’ does it “wrong” aka at 22px it doesn’t use the monochrome icons.
I did not mess with the theme or installed/uninstalled any, I just switched between themes and applied/reapplied them. From manually applying the “Symbols” aka icon themes of a theme while keeping everything else from the previous theme I found out which theme uses which icons. The results is what you can see above.
I hope this was helpful, thx.
Btw, should we move this to an independent thread?
Thx for the reply.
Applying Breeze the icons work as intended, monochrome.
If I afterwards directly apply the Breeze Dark global theme the icons are colourful again. Checking which icon pack is used for which Theme, I can see that Breeze uses the “Breeze” icons while Breeze Dark uses the Breeze Dark icons.
and that’s what you would expect, right? i use breeze dark with breeze dark icons and it works perfectly
edit: i suspect you misreported breath as breeze in your reply, but it does not change the fact it works for me on a close to 6 year old install. If you have problems on a very fresh install, then it might be an issue with recent install media.
I can see that Breeze uses the “Breeze” icons while Breeze Dark uses the Breeze Dark icons.
Ok, we all seem to be right about this.
I was able to reproduce this issue within a live environment:
Switch to Breeze (Dark) Theme(up until now everything works as intended)
Switch display scale above 100%
Icons are not monochrome anymore(after relaunching Dolphin etc)
Works on both X11 and Wayland, however setting the scale to a value below 100% (on Wayland that is possible) doesn’t trigger the unintended behavior.
Maybe some of you could confirm that this issue exists for them as well, if not at least in a live environment.
If someone can confirm this issue I could open a separate thread in case @cscs’s mention is not sufficient.
