When I draw a transparent picture in a picture window it uses the standard window colour as background instead of the real background.
Code to test:
alias bugtest {
window -pB +dL @lagbar1 441 134 121 19
drawfill -r @lagbar1 12107912 15728807 1 1
drawpic -hc @lagbar1 90 0 media\gfx\toolbar\lagbar2.gif
}
The file lagbar2.gif is a transparent picture. You can create your own one or download this one
here.
Possible workaround:
Use
drawfill after
bugtest to change the wrong background colour.
drawfill -rs @lagbar1 12107912 13684944 0 0 90 0 91 0
