Help -> System Info reports -1 MB for "Installed video RAM" when in fact it should be 4096MB.

How to repeat:
1. The particular video card I am using is the ATI Radeon Pro WX4100. This card has 4096MB of RAM. I suspect any video card with greater than 2GB will also result in a bogus reading.

2. Start Workbench and select Help -> System Info; here are the relevant results--note the bogus value for "Installed video RAM"

MySQL Workbench Community (GPL) for Windows version 6.3.9 CE build 10690321 (64 bit)
OS: Microsoft Windows 7 Professional Service Pack 1
Active video adapter Radeon Pro WX4100 Graphics
Installed video RAM: -1 MB
Current video mode: 1920 x 1080 x 4294967296 colors

Suggested fix:
I suspect someone used a signed integer for this value instead of an unsigned integer and/or the incorrect print format specification was used. Thus any value over 2GB overflows and shows as a -1.

I don't understand why a screenshot is necessary when I've already provided the relevant output from Help -> System Info?
[25 Apr 2017 0:02] J Scavok
As we both know, the output from Help -> System Info is text.

I'm simply trying to understand why you're requesting a screenshot of this text, "Installed video RAM: -1 MB"?

Piriform Speccy correctly reports the installed video RAM is 4096 MB

Windows correctly reports the "Dedicated Video Memory" as 4096 MB

Yeah, it's 4096 MB

Thank you for the feedback and screenshot.
Even on a smaller environment observed negative count.
