Bug still exists in today's OB patch. It is engine-wide, across all modules that I currently own and was able to test.. Client integrity was checked, fxo and metashaders folders were deleted and recreated directly before these were taken, no mods or non-standard textures are in use.
Since the attachment limit seems to be three for this post, I've uploaded a selection of three; the imgur album with all of my collected and labeled screenshots can be found here: https://imgur.com/a/Jxzi8eN
The raw screenshots can be provided if necessary.
Please note that the highlighted areas are simply where the bug is most visible, not the only areas affected. In modules where the cockpit is not included, it's because the colors are weathered/muted enough to avoid the bug, most notably Razbam's Mirage and Harrier cockpits. Again, not that the bug isn't present at all, but too difficult to see.
Red is the most prominently glitched color, but if you will observe the Su-27 screenshot, sufficiently bright blue will also reproduce it.
I hope this information is in some way helpful.
