It could be the graphic driver inside the VM of Fedora Workstation OS?
The way I understand Qubes graphic driver management, is that you need Qubes
specific graphic driver in the VM since the graphics are (translated) to/from
the system graphics, which again uses more common Linux drivers to/from the
bare metal hardware. In other words, you might possibly need a second graphic
driver inside Fedora Workstation OS to properly translate the graphics, the
issue might not be related to your actual graphic card, but rather the graphic
translation between OS/VM.
This too should be the reason why heavy graphics rarely works too well in VM's
since it essentially is a translation or emulation before it arrives at the
actual system graphic driver, and the translation isn't of the best or
snappiest quality.
I could be wrong, this is only a guess of mine, but it may be worth considering
before you go out buying another graphic card though.
A potential worst case scenario would be if you bought a new graphic card and
the exact same issue happens again because of the issue translating the
graphics over from the VM to Qubes.
Also I use i5-6500 my self, I never had issues with it, but then again I also
never installed Fedora Workstation on it.
A potential worst case solution may be to buy a cheap graphic card as you
suggested yourself, however instead use the card to use GPU Passthrough
directly into the Fedora VM, thus bypassing the need of a second graphic driver
altogether. At this point should act like any other OS regarding the graphics,
talking directly to the graphic card (Make sure the graphic card support GPU
Passthrough).
It may or may not be a lot of work to get GPU Passthrough working though, I
failed with my GTX 1060 Nvidia card, since newer non-quadro Nvidia card models
typically do not allow for virtual environments, due to Nvidias market
segmentation design.
AMD/Intel should however more commonly allow for Virtual GPU Passthrough,
though, make sure they support first.
I'm not any expert on this, just floating ideas, and since I never managed to
get it to work my self, I cannot tell you if it will work (Possibly because I
got a non-GPU Passthrough card, but I can't say for sure, I need a new graphic
card before I try again my self).
If you try a GPU Passthrough, be sure to read up on it or hopefully someone
with better knowledge will be able to fill in. GPU Passthrough sure as heck was
a can of worms for me, so I'm not endorsing the idea by anything but highly
experimental and only if you got time/money to pass to try see if you can make
it work.
