Tray rendering issues

[fishman]

Describe the issue

I'm having rendering artifacts in my polybar systray.

It seems to be especially bad for QT icons. But even things such as the nm-applet have these artifacts. It's seems like when it draws it will draw over the previous state. So when nm renders a loading waiting circle it will stay there with the rest of the icon.

Easiest way for me to trigger it is reloading the polybar config with pkill -USR1 polybar.

I use a settings daemon with 115 DPI. I don't have any hidpi autoscaling enabled either.

• I tried the arc theme.
• I use the papirus icon theme.
• For QT I use qt5ct
• I also tried the adapta themes with kvantum in QT

To Reproduce

tray-maxsize = 33 tray-position = right tray-padding = 2 tray-background = ${root.background}

Environment:

• bspwm with wmname LG3D

I didn't notice https://github.com/jaagr/polybar/issues/1143

I can confirm that https://github.com/jaagr/polybar/pull/1415 makes it a little better, but things like networkmanager still get garbled up after a while.

I'm closing this then as a Duplicate of #1143.

The tray will be replaced in the future and we weren't able to find the cause for this issue in the current implementation.

@patrick96 is there any known configuration where this doesn't happen? I'd just switch to that in the meantime.

I don't think so. The only sure way is to not use the tray in polybar and use another dedicated tray program and place it where the polybar tray would be.
