Steam Beta - Client inner window turns black on resize

[DonKatsu]

Your system information

• Steam client version (build number or date): 1682634349
• Distribution (e.g. Ubuntu): Fedora 37 KDE (Wayland)
• Opted into Steam client beta?: Yes
• Have you checked for system updates?: Yes

Please describe your issue in as much detail as possible:

Resizing or minimizing and restoring the Steam client causes the inside of the window to turn black. Example screenshot.
Navigating to other pages continues to show the black inner window. The only way I've found to fix it is to open the library page.
Resizing or minimizing and restoring Steam while in the Library doesn't cause it to happen.

It happens whether "GPU accelerated rendering in web views" is on or off.

Steps for reproducing this issue:

1. Resize or minimize Steam client window
2. Try navigating to a different page
3. Open library to fix

The issue only happens if you maximize moving the window to the top of the screen (or use Win+up on the keyboard), or if you resize it moving from top to middle of the screen (Win+down). So you can use the maximize button at the top right as a workaround.

And yes, the black screen get fixed when going to the library section.

The same still happens here with Steam-Version: 1686880776

Can also confirm that this still occurs with Steam v1688792985. (Running Fedora 38 KDE Wayland w/ Mesa 23.2.0-git).

Switched to beta to check but in ver 1690426635 it is still happening - worse the same happens when starting games (ex. cyberpunk - same black square filling the game window). Started after switching from nvidia 4.XX to 5.XX drivers - currently on 535.86.05

Resolved

I'm not sure if it's from this issue or a new one, but since a few beta updates ago my Library tab is acting up.

My Steam is set to open to the Library tab on launch. It behaves properly when Steam is initially launched.
When opening Steam to the Library tab through the notification panel icon from a closed window, it renders normally but appears unresponsive. It shows what the Library tab was last opened to, but it's still loading the default library page.
The cursor changes as I hover over clickable elements and text. If I change what game's info is shown by clicking one in the list of the Library page, the visual of the page doesn't change but the contents do.

This applies to UI elements as well such as the status indication color of my username next to the window controls.
If I launch a game from the notification panel icon while the window is in that state, it stays blue instead of changing to green.

Resizing the window updates what's shown and afterwards continues to properly render as long as the Steam window remains open. Changing tabs works when the Library is in its stuck state, but going back to the Library tab doesn't fix it.

The other options such as Store or Friend Activity show the same stuck UI behaviors, but renders a black page.
If I go from being on the Library tab, close the window, and open the Store from the panel icon, Library is underlined and in blue.

This seems resolved with Beta update 1690583737. But the original issue remains.
