White lines in Oncoprints - Rasterization issue?

[w2felix]

I have an issue with Oncoprints, which has been described here (#621) but did not solve my issue:

ComplexHeatmap 2.21.0, magick installed

I tried to follow all suggestions like:
use_raster = TRUE, raster_by_magick = TRUE

but that did not help and also turning rastering of produced the same white lines:
use_raster = F

when I have small width, the top anno does not look nice (n = 514, no NA entries, so this should not be the reason):

As soon as I increase the width:

library(ComplexHeatmap)

col = c(`>100 TPM` = "darkgreen")

alter_fun = list(
  background = alter_graphic("rect", fill = "lightgrey"),   
  `>100 TPM` = alter_graphic("rect", width = 1, horiz_margin = unit(0, "pt"), fill = col[">100 TPM"])
)

oncoPrint(oncoprint_data,
           alter_fun = alter_fun,
           col = col,
           row_order = 1:nrow(oncoprint_data), 
           right_annotation = NULL,
           row_names_side = "left",
           pct_side = "right",
           use_raster = TRUE)
