Some icons (launchers) become pixelated from time to time.

[lomapur]

Hello!

Sometimes some icons (launchers I suppose) in the dock get pixelated (seems pretty random, so as for now I didn't really find any concrete trigger for this). Plasma restart seems to fix the issue, temporarily.

EDIT: Closing application (in this instance Chromium) fixes the issue as well.

I havent seen this before... are u using zoom factor 1.0 ?

[lomapur]

Nope, zoom factor 1.50.

When zooming (hoover over launcher) the pixelation goes away for the time it's zoomed (for all launchers), then goes back to normal size and being pixelated.

EDIT: this issue feels funny.. While having the icons as on picture above I opened Dolphin, and to my amazement issue fixed itself once again.. until I closed Dolphin, when launchers once again became pixelated.

[psifidotos]

it is so strange.... I am using QIconItems for the icons that is plasma technology (not in my side) but either way I will have to think it over...

[psifidotos]

@lomapur can u give me some feedback?

1. what icon size are u using?
2. if you change the icon size what is happening?

[lomapur]

@psifidotos I would love to, but I was distrohopping a bit and I for the love of all that's saint couldn't get Panel installed under Plasma 5.8, so for the time being I'm not using Now Dock and it's not installed here :) will install it without Panel and report back, ok?

EDIT:

1. If I recall correctly icon size was 48px (or automatic).

As for now I wasn't able to reproduce this issue without Panel underneath Plasmoid yet, so it may have to something in common with plasmoids on Panel (as pixelation started to show up mainly when I hovered over Folder/Clock).

[psifidotos]

@lomapur, if you want to install Now Dock Panel in Plasma 5.8, the easiest way is to use the command,

sh install-local.sh

it should install it correctly even in Plasma Desktop 5.8

As for now I wasn't able to reproduce this issue without Panel underneath Plasmoid yet, so it may have to something in common with plasmoids on Panel (as pixelation started to show up mainly when I hovered over Folder/Clock).

• this is very strange... pixelation was showing in the launchers or at plasmoids Folder/Clock ?

it could be a cache issue if it can be reproduced again with Now Dock Panel reinstallation...

[lomapur]

Pixelation was showing on launchers when hovering over plasmoids added to panel.

[psifidotos]

that is so strange... I will wait for your feedback when you manage to install again Now Dock Panel in Plasma 5.8...

[psifidotos]

@lomapur if you add the Now Dock plasmoid in a regular panel with some plasmoids around it,
does this issue appear?

[lomapur]

Reinstalled (Thanks for tip!) and there is no problem like that when placed in normal panel (at least I didn't stumble upon one), I deleted normal plasmoids from Panel (Now Dock Plasmoid stayed) and the issue went away.

[psifidotos]

so strange...

and when you re add some plasmoids the problem reappears?

can you make a screenshot also for your Now Dock Panel configuration dialog in order to try to reproduce some way?

[lomapur]

Yes, re-adding plasmoids makes problem reappear.

Settings:

Hovering over Folder (Hovering over Lokalize or other last-before-Folder launcher/task icon have the same effect); it went back to normal though, couldn't reproduce the main issue yet.

[psifidotos]

I can not reproduce it yet...

Things to test please:

1. changing the plasma theme does it make any difference?
2. what graphic card and driver are u using?
3. changing the icon size to 64 does it make any difference?

[lomapur]

After deleting folder problem is still here:

1. Changing the plasma theme does not make any difference unfortunately.
2. Intel HD 3000 / i915
3. No artifacts for 64px!

[psifidotos]

so this problem appears to you only for 48px. icon size?

[lomapur]

Seems like it, yes.

[psifidotos]

two more things :)

1. if you set zoom factor 1 does the issue remain?
2. if you increase or decrease the panel's height, does it make any difference?

[lomapur]

1. No issue with zoom factor 1.
2. Panel height change does not make any difference.

ALSO: changing zoom factor solves issue (so pixelation happens only for 48px/1.50 zoom)

[psifidotos]

I see...

and a last question,
are u using now dock panel 0.3.1 or the master branch ?

[lomapur]

The last one from the Store (0.3.2) installed from Get More Widgets... menu.

[psifidotos]

this is the plasmoid (version 0.3.2), the last store version for the panel is (0.3.1)

[lomapur]

Oh, sorry, I misread; master branch then.

[psifidotos]

ok ... strange issue...

I will think it more... :)

[psifidotos]

@lomapur , things may have been improved in master branches for this... Now the user can choose also more icons sizes and may the pixelation has been solved...

[AndydeCleyre]

This happens reliably for me with the latest versions of panel and plasmoid, and the slack-desktop app, when Slack is closed. When it is open, the icon looks good, but when closed, all pixelated. I have my zoom factor set at 1.0, and icons set at 128 px.

[psifidotos]

can you send a screenshot also please?

[AndydeCleyre]

[AndydeCleyre]

Oh, I'm stupid. It's the slack .desktop file's fault. Sorry for the noise.

[psifidotos]

Oh, I'm stupid. It's the slack .desktop file's fault. Sorry for the noise.

what was the reason ?

[AndydeCleyre]

My slack.desktop had a hardcoded icon url. Changing it to just the name and dragging it onto the dock solved the issue.

[psifidotos]

nice!!! This could be useful to others also!!!!
