Possible bug: v10.0.0 PNG logo only displayed on first PDF page

Bug

Since years I use the same logo image file. It's a normal, standard PNG with a transparent background. It worked perfectly until v9.0.3. After the upgrade on v10.0.0 the PNG logo is shown only on the first page of the invoice (or proposal). Of course I use native PDF reports, so crabe or azur.
If for testing I use a JPG logo, it works on all the pages as expected. The problem seems only with PNG files (tried many).

@eldy As current version 6.2.26 of TCPDF is considered obsolete and no new release has been released since 16 Oct 2018, should me make an exception an patch htdocs/includes/tecnickcom/tcpdf/tcpdf.php file directly on Dolibarr repo ?

Update to v12 and reopen if the problem persists.
