Your system information

• Steam client version (build number or date): 1733265492 (Stable) / 1734061824 (Beta)
• Distribution (e.g. Ubuntu): SteamOS 3.6.20 / 3.7.0 (Deck) and Manjaro w/ Gnome 46 (Desktop)
• Opted into Steam client beta?: Yes. Issue is present on both Stable and Beta
• Have you checked for system updates?: Yes
• Steam Logs: steam-logs.tar.gz
• GPU: AMD Van Gogh RDNA 2.0 (Steam Deck) and RX 7800XT (Desktop)

Please describe your issue in as much detail as possible:

When releasing Steam + L1 to exit out of magnification, the device can occasionally remain magnified. The user must press the shortcut a second time or toggle the Steam / Quick-Access Menu to disable the magnification. Magnifier controls do not function in this state, it only maintains magnification (unless the game is set to Mouse / Keyboard in which case you can still pan around). Attempting to open the Steam or Quick-Access Menu while while the magnifier shortcut is being held will also disable magnification and cause the issue to occur upon release.

Steps for reproducing this issue:

1. Launch any title on Steam Deck.
2. Press and release Steam + L1.
3. Repeat #⁠2 until the issue occurs.

Reproduction Rate: 1/3

Affected Platforms

• LCD / Jupiter: Yes
• OLED / Galileo: Yes
• Desktop Deck-like session (gamescope -e -- steam -gamepadui -steamdeck): N/A
• Desktop: N/A

Note: Magnification does not appear to be supported on Desktop even though it appears in the Steam Button Shortcuts screen in Big Picture Mode. Running in a Deck-like session (i.e. with Gamescope) also does not appear to allow this functionality (https://github.com/ValveSoftware/steam-for-linux/issues/9188)

Actual result

• Sub-menu visually collapsed onto the primary context menu and the primary menu's visual styling partially breaks.

Expected result

• Context menu and sub-menu remain visually consistent prior and subsequent to a title being launched or closed on another device.
• As noted here (https://github.com/ValveSoftware/steam-for-linux/issues/11571#issuecomment-2541816415), an option to enable magnification toggle would also be a viable solution to allow the this behaviour to be more intentionality used by users.

Notes

• This can also be reproduced via ... + L1.
• This issue could not be reproduced when using an external controller (PS / Xbox + L2 / LT).
• This is purely speculative, but it seems like the button release order affects the reproducibility (i.e. if the Steam button is released first it seems to repro easier).
