Summary0033793: Imagelist Editor - non default transparency
DescriptionThis issue happen when you load images with multiple resolutions to imagelist (via Add more resolutions... button) and you need non-default transparency color (default transparent color is bottom-left pixel).

After changing of transparency color in combo-box (I used Fuchsia), basic resolution is changed correctly while higher resolutions are scaled from the basic resolution - it results in blury images.

Images (16,a 24 and 32 px) are bundled to demo.
Steps To ReproduceRun demo.
On the right you can see images displayed correcty - from three separated imagelists.
On the left are higher resolution displayed incorrectly, all from one imagelists. Only basic resolution is correct.
Additional InformationLazarus 1.9.0 r58035M FPC 3.1.1 x86_64-linux-qt
Fixed in Revision
