12.3 and certaing PNGs: error rendering them

[rgomezc 0]

Hello,

 

I noticed since upgrading to 12.3 that certain PNG are rendered incorrectly by the TPngImage class. For instance, the attached PNG.

 

I have opened a bug report on Jira/QP: https://embt.atlassian.net/servicedesk/customer/portal/1/RSS-3382.

 

Just wondering if anybody else can confirm this, and if somebody can think of a workaround?

A image showing what "rendered incorrectly" looks like would make it a lot easier to confirm reproduction.

Sorry, I attached it to the QP item but not here. This is an example from a vanilla RS 12.3 installation on a VM:

 

 

That object has this code on the dfm:
