VMs are blurry without Retina mode

[LostInCompilation]

Every VM is quiet blurry when retina mode is disabled. I tried every scaling option there is with no improvement. It's probably a configuration error on my side. Or is it just expected?
Retina mode is not always an option, since some older systems can't support these high resolutions or become really slow.
Different display devices make no difference.

Is this new to 4.1.5 or has it always been the case? If it’s always been the case I think what you see as “blurry” is what’s expected from non-hidpi and you’re just used to it.

This was always the case. I did some experimentation. For example if I install WindowsXP using the config file from the UTM website, which uses the SPICE QXL GPU device, the screen is blurry. Even when I change the display device afterwards. When I install WindowsXP with virtio-vga-gpu it is not blurry.

Here are screenshots comparing the two. Same resolution, no retina mode, running with same display device and VM settings.

Perhaps the example config uses a different upscaler/downscaler?

Oh well. I messed up. Somehow I screwed up with the upscaler settings. Thought I tested them all...
Yeah nearest neighbour for upscaler is working fine now.

"Yeah nearest neighbour for upscaler is working fine now." what does that mean? I have the same issue

Yeah I have the same issue. What the frick do you mean "nearest neighbour for upscaler"??

You can select the upscaler in the VM settings.
