Out of the box text in the icon editor looks awful. (See attached image, which is better looking than most.)

LabVIEW 2016 64-bit, CentOS 7 Linux OS
We have tried many things to get this to work, to no avail.
Does anyone have a solution?
I wanted to cross post metux's discovery here asap, and have a separate discussion.
Metux's original post:
The recent Linux driver package introduces a CRITICAL security vulnerability:
It adds additional yum/zypper repos, but explicitly disabling package signing and using unencrypted HTTP transport. That way, it's pretty trivial to completely takeover the affected systems, by injecting malicious packages.
DO NOT INSTALL THIS BROKEN SOFTWARE - IT IS DANGEROUS !
CERT and BSI are already notified.
More out of curiosity than of hope: has anybody any idea why SVs are almost unsupported on linux? By almost I mean that controls and indicators cannot be bound to shared variables, and that shared variables cannot be programmatically created and looked up. I know that SVs hosted on windows can be accessed in linux LV using datasocket nodes, but that is all it gets. And it has been said that datasocket is despicable. What are the missing pieces that make SV windows-only?
I didn't find much in the canonical places, so I posted a dumb zero-kudos attracting idea.
Currently working on VeriStand custom devices, I'm facing a 'huge' problem when debugging the code I make for the Linux RT Target. The console is not availbale on such targets, and I do not want to fall back to the serial port and Hyperterminal-like programs (damn we are in the 21st century !! )...
Several years ago (2014 if I remember well) I posted an request on the Idea Exchange forum on NI's website to get back the console on Linux targets. NI agreed with the idea and it is 'in development' since then. Seems to be so hard to do that it takes years to have this simple feature back to life.
On my side I developped a web-based console : HTML page displaying strings received through a WebSocket link. Pretty easy and fast, but the integration effort (start server, close server, handle push requests, ...)must be done for each single code I create for such targets.
Do you have any good tricks to debug your code running on a Linux target ?
I've got a customer that wants to zip/unzip files on their cRIO-9035, so I had them playing with the OpenG Zip tools to see if it would fit their needs. Although they've found that they can zip files on their cRIO just fine, they find that they get disconnected from their RT target and the shell shows the following error message:
LabVIEW caught a fatal signal 15.0 - Recieved SIGSEGV Reason: address not mapped to object Attempt to reference address: 0x0x10000000 stdin: is not a tty
The zip file they're testing with includes two simple .txt files with short strings in them ("booya" and "booya2"). This file unzips just fine on the host PC with the "ZLIB Extract All Files To Dir" VI, but when copied over to the cRIO and unzipped via the same VI, it only unzips the first text file and the resulting file doesn't have any text in it.
I've attached a copy of the project and the zip file I used to reproduce this behavior using a cRIO-9033 that I had on hand. (The only thing I can't provide is the cRIO >_<)
Could anybody tell me what I'm doing wrong? Any suggestions as to what other workarounds I could take to zip/unzip files on a LinuxRT target would also be very much appreciated!
