Hey, I'm one of the original bug reporters. Thanks for working on this! It works fine for me now too. I also use wayland and a recent Ubuntu (19.10).

Actual results: Firefox adapts its highdpi settings to the value in unity-control- center. However, it will round the scale to the next higher value, e.g. 2.0. This means everything is much bigger than it should be. If I set devPixelsPerPx to 1.5 manually everything looks fine. So there must be some bug in firefox that is reading this value as an integer. Expected results: Firefox should use the actual floating point value.

It basically removes the rounding applied when reading the current DPI from gdk_screen_get_resolution(). I have tested this and it works as expected: the Xft/DPI value is read from XSETTINGS, returned in gdk_screen_get_resolution() and then correctly applied to the content rendering as well. This is consistent with the UI rendering, which already gets scaled correctly at all Xft/DPI values > 96. I hope this can be included.

This probably comes from the fact that GDK_SCALE and GDK_DPI_SCALE only accept integer values (and 0.5). There is no _technical_ requirement for this, though. https://developer.gnome.org/gtk3/unstable/GtkSettings.html#GtkSettings --gtk-xft-dpi accepts granularities of 1/1024th DPI. Also, the "component" of this bug should probably be changed to Gtk:Widget or seomthing else.

The DPI scale is just one part of it - the application is supposed to also provide hi-res graphics (pictures, icons, controls) for those modes. IIUC This is also a reason why it's integer scale - to easily scale bitmap images like icons or to provide hi-res icon set.

As I see it, the DPI (referred to as font scaling, gtk-xft-dpi or Xft/DPI setting) operates independently from the "global" GDK_SCALE setting. If I am reading bug #1131978 correctly, both are used to determine the overall "scale" within Firefox. That is, the font scaling read from gdk_screen_get_resolution is not affected by GDK_SCALE (but maybe by GDK_DPI_SCALE?). In any case, it is obvious that the *UI* (is it called chrome?) part of Firefox scales correctly (as seen for example in the font size in about:settings and the tab font size), but the *content* part doesn't. After applying this patch, both scale consistently.

Weird. I just upgraded to Zesty. Firefox now seems to autodetect changes in the pixel scaling (no restart needed), but it rounds again to integers >.< -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to thunderbird in Ubuntu. https://bugs.launchpad.net/bugs/1500282 Title: pixel scaling seems to be rounded to integers Status in Mozilla Firefox: Confirmed Status in Mozilla Thunderbird: New Status in firefox package in Ubuntu: New Status in thunderbird package in Ubuntu: New Bug description: Firefox adapts its highdpi settings to the value in unity-control- center.
