Missing top&bottom line in an icon in xfce4-panel (systray)
There are two problems:
- The 1st (top) line of the image is missing from the downscaled icon shown in
xfce4-panel
- The bottom line of the image is missing from the downscaled icon shown in
xfce4-panel
Settings:
- The height of
xfce4-panel
is set to 48 pixels ("Panel Preferences" => "Row size (pixels)") - The width and height of icons is configured to 48 pixels ("System Tray Settings" => "Fixed icon size (pixels)")
- The image viewer (
geeqie
, see below) is using bilinear scaling - xfce4-panel 4.17.2
Current workarounds for this issue:
- Increase the height of
xfce4-panel
by 2 pixels (from 48 to 50 pixels), or - Decrease the
systray
fixed icon size by 2 pixels (from 48 to 46 pixels)

The same icon, but downscaled from 128x128 to approximately 48*48 pixels in an image viewer (geeqie
+ kmag
