I'm curious to find out about RHEL 6.
The version of Qt 5 on RHEL 6 has, shall we say, "not good" HiDPI support. One customer has now standardized on $300 4K monitors as their new "desktop standard." Many of the screens now look like doo-doo all because a better monitor was installed. Video card, driver, OS all remained the same. This has lead to some serious raised voices.
I don't currently have a 4K monitor to test any of this with. I haven't even looked into how CopperSpice supports it. Do we have to do the hokey
Code: Select all
setAttribute(Qt::AA_UseHighDpiPixmaps, true);
Or is it just automagic because what is under the hood is smart enough to identify monitor resolution and simply adjust everything?
These two things:

Combined with this slide show
https://meetingcpp.com/mcpp/slides/2019/High%20Performance%20Graphics_MeetingCpp1655.pdf
kind of imply it is automatically handled under the hood via Vulkan. The 3D imaging comment on the slides was kind of interesting too, but for someone else.
I do disagree with one point on the slides.
average around 1000 cores
Many in the field have 16 or fewer CUDA. The GeForce 630 family was wildly popular because Newegg was selling them for < $50. They had 2Gig of RAM and 384 CUDA. I own at least 3 of those. Lots of my customers have them as well. They were the best bang for the buck. The GTX 650 cards appear to be the current replacement and they still have only 384 CUDA.
At any rate, the real question here is two fold:
1) Can CopperSpice build on RHEL 6?
2) When built on RHEL 6 will it have the full HiDPI support that exists on RHEL 6
