--- Comment #30 from Fabian Vogt
OK, thanks all for your investigations. This all sounds very promising.
So, to summarize (please correct me if I am wrong):
- There was a bug in the Qt libs.
- We now have a fix as a patch on top of our Qt libs build.
- That patch was also sent upstream, but of course it will take a while until the fixed version trickles down to us again.
Is there anything left for the installer to do? I don't see anything.
Yes, consider moving from "-depth 16" to use the Xvnc default, see comments 26 and 27. (In reply to Stefan Hundhammer from comment #29)
Since Qt now does all pixel rendering locally into a pixel buffer and sends that whole buffer to the X server (no more Xlib primitives), does it even matter if the X visual has an alpha channel? I don't think it should; it should all be done on the Qt level before the pixel buffer is even sent.
It doesn't - the X11 target surface doesn't use alpha in this case. The difference was RGB565 vs. RGB888. -- You are receiving this mail because: You are on the CC list for the bug.
