Goverlay 1.9.0 stabilizes nightly build, adds Russian translation and MangoHud config fixes
The Qt6 performance tool interface for Linux gamers is now production-ready with improved sandbox handling and a new contributor adding eight pull requests in one sprint.
Goverlay 1.9.0 release is now available on GitHub. If you're juggling MangoHud, vkBasalt, and OptiScaler on Linux, this is the visual interface that generates your launch commands and per-game config files without the manual editing. The update lands with Russian language support, fixes for MangoHud config derivation, and better sandbox handling.
Goverlay is a Qt6 app built on Free Pascal and Lazarus. It wraps performance tools like gamemode and Proton tweaks into a card-based UI. It creates per-game config directories and spits out the bgmod wrapper command you paste into Steam or Lutris. The project sits at 1,400 stars on GitHub. It's not huge, but 81 open issues suggest people actually use it and aren't afraid to file bugs.
MangoHud state and i18n
The MangoHud fix addresses a config state bug that likely frustrated nightly users. Previously, the UI derived MangoHud config state from button captions. If the caption changed or got truncated, the config went out of whack. The fix drives buttons by actual state. Keep in mind that @wehrwolfmann also wired up the LCL translation mechanism. Russian is the first non-English language supported. Message box text is moved to resourcestrings so translators can't accidentally break configuration values.
On top of that, the release improves module detection for lsmod output. The old logic could trigger false positives on systems with truncated output. The Flatpak sandbox handling is also tighter. There's a build system fix for a duplicate identifier error in cmem as well.
What you need to know
You can grab Goverlay via Flatpak, AppImage, or repos for Arch, openSUSE, and Solus. The AppImage sits around 67 MB. You'll need Nerd Fonts installed for the icons, and you must have the underlying tools like MangoHud or OptiScaler installed yourself. Goverlay doesn't bundle them. It just manages the configs.
The release adds support for PROTON_VKD3D_LOWLATENCY for latency-sensitive titles. There's also a fluid resizable window now, with size and position restored across sessions.
It's a pretty specific tool for a specific crowd. If you're the type who manually edits .conf files for every Proton game, Goverlay saves you time. The promotion from nightly to stable is a fair confidence vote from the maintainer. However, at the same time, eight open issues suggest the sandbox and testing work is still a moving target. The addition of i18n is a good step for growth, though. It signals the project is maturing beyond a single-language audience.
Head here for the flatpak install. If you prefer the AppImage, you can grab it soon from the releases page.
