`Window Preview Size to Monitor Size Ratio` fails to take into consideration display scaling on Wayland #212

Open FelixFourcolor opened 6 months ago

FelixFourcolor commented 6 months ago

The property allows values from 0 to 1. However, if the display scaling is 200%, the value only goes up to 0.5; you can set it above 0.5, but it will be rendered the same as 0.5. And similarly if the display scaling is 300%, the value only goes up to 0.33.

This bug is only seen on Wayland.

Gnome 45 Extension v.70

Hey thanks for the report! I'll look into this like now because I'm on holiday with nothing to do. Is this a new thing? Or seen in previous versions too?

FelixFourcolor commented 6 months ago

If I remember correctly v.70 just came out today? Then I'm sure it's also in v.69, but I can't remember before that.

dsheeler commented 6 months ago

Yes, v70 just today. Thanks!

It seems that this behavior is also app-dependent. Most apps behave as I described above, but I found that vscode and steam are scaled properly.

To exaggerate the effect I show Window Preview Size to Monitor Size Ratio=1 and display scaling 300%.

@FelixFourcolor, I don't fully understand the situation. It might be that xwayland apps don't work but native wayland apps do or vice versa. Or something more complicated, like some xwayland apps work and some don't...

FelixFourcolor commented 6 months ago

@dsheeler I didn't think about it, but that makes sense. I think xwayland apps are scaled correctly, only native ones are broken.

@dsheeler any updates on this bug? It still bugs me to this day.

dsheeler commented 1 month ago

No updates, sorry. My last comment still describes my state of understanding which is my understanding is incomplete. I feared it was the case that it's up to the application to scale properly in xwayland and I couldn't really do anything about it. I forget what the app needs to do at this point. I also find it hard to get motivated because I sitll use X11 and this is a "temporary" problem that exists only as long as xwayland is necessary. But how long will that be???

FelixFourcolor commented 1 month ago

Unless I misinterpreted what you said, I think you got it the other way around. It's native wayland apps that don't scale properly, xwayland apps work.
