- Ubuntu 10.04 (lucid)
- LWJGL 2.4.2
Even when the byte buffers passed to Display.setIcon
contain proper alpha data, the displayed icon(s) will only have on/off transparency. This is especially visible when using the Alt+Tab window switcher. I noticed that the icons of other applications (i.e., non-LWJGL ones) don't have this problem, so apparently there's some level of support for 8-bit transparency that LWJGL doesn't currently make use of.
A similar limitation in the Windows port was removed some time ago (r3227).
