https://bugzilla.suse.com/show_bug.cgi?id=1227124 Bug ID: 1227124 Summary: XWayland applications appear blurry and have resolution issues when fractional scaling is enabled under GNOME Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: x86-64 OS: openSUSE Tumbleweed Status: NEW Severity: Major Priority: P5 - None Component: GNOME Assignee: gnome-bugs@suse.de Reporter: reiokorn@tutanota.com QA Contact: qa-bugs@suse.de Target Milestone: --- Found By: --- Blocker: --- Summary: When fractional scaling is enabled on GNOME (experimental option), XWayland applications, such as Steam, OnlyOffice, and Wine, experience significant usability issues. These include blurry appearance and the inability to set native resolutions for games. Description: When fractional scaling is enabled on GNOME: 1. Blurriness: Applications not yet on Wayland, like Steam and OnlyOffice, appear blurry when using XWayland. 2. Resolution Issues in Wine: For gaming applications running on Wine (also not yet on Wayland), the native resolution option becomes unavailable. Users are forced to choose between: - 200% scaling with 0.75 font scaling (equivalent to 150%) - 100% scaling with 1.5 font scaling This forces users to decide between larger fonts or larger icons, neither of which is ideal. Additional Issues: - While Wayland-native applications work as expected, XWayland applications face these issues. - The mentioned scaling options work for GTK applications, but QT applications become too small and require additional scaling adjustments through environment variables. Potential Fix: There is a pending merge request that aims to allow XWayland applications to scale themselves, which could circumvent these issues: [GNOME Mutter Merge Request #3567](https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3567). Steps to Reproduce: 1. Enable fractional scaling on GNOME. 2. Launch any XWayland application (e.g., Steam or OnlyOffice). 3. Observe the blurry appearance. 4. Attempt to set native resolution in a game running on Wine and observe the unavailability of native resolution options. Expected Results: XWayland applications should scale properly and maintain clarity, and users should be able to set native resolutions in Wine without being forced to choose between suboptimal scaling options. Actual Results: XWayland applications appear blurry, and native resolution options are unavailable in Wine when fractional scaling is enabled. System Information: - OS: openSUSE Tumbleweed # VERSION="20240625" - Desktop Environment: GNOME - Fractional Scaling: Enabled - Applications Affected: Steam, OnlyOffice, Wine (among others) This issue significantly impacts user experience, requiring cumbersome workarounds and affecting a broad range of applications, when using a HiDPI monitor and the need to use fractional scaling on GNOME to make it usable. -- You are receiving this mail because: You are on the CC list for the bug.
