One quarter of screen displaying a white box in KDE Plasma 6 after MEGARELEASE. (WAS) Unable to load usable X11 session after Tumbleweed update:

Created attachment 874771 [details] inxi -Gxx output in TTY3 Hi, I decided to update an i386 Tumbleweed machine here to the latest 20240506 snapshot there were many many packages listed for update (1900+). I used snapper to create a snapshot manually prior to the update. The update appears to have completed fine without incident. I then powercycled the machine. Now when the SDDM desktop display manager is displayed, I am able to select X11 session type then enter my password and login. Once logged in, the desktop is for the most part unusable. Menu button is covered by workspaces, taskmanager is partially blank, (konsole is also unusable). I can then switch to TTY1 and enter my username and password. Passing 'inxi -Gxx' displays the following -> https://paste.opensuse.org/pastes/f42c153b3d71 I have added an attachment to this report of the inxi -Gxx output in a photo as well. It appears to me that Xwayland is being used even though I have selected the X11 session type at SDDM login. Looking through /.config/kdeglobals (using TTY1) does not show -> [QtQuickRendererSettings] SceneGraphBackend=software I know this is probably not a software rendering issue. Previously I have forced software rendering by editing /etc/environment and adding -> QT_QUICK_BACKEND=software KWIN_COMPOSE=02ES Do you believe this may be an issue with a newer version of Mesa now? Can you tell me the best way to force X11 session to load? -Best Regards

The inxi report may be deceiving to some people WRT X11 and Wayland. "with Xwayland" does not mean a Wayland X session is running.

Very good to see your comment here. Ok I understand about Xwayland more now from your comment. The inxi report may be deceiving to some people WRT X11 and Wayland. "with Xwayland" does not mean a Wayland X session is running.

The topic seems to have changed now. One quarter of the screen is filled by a white box. I can change a tab (application) and somewhat get it to disappear temporarily but it comes back. Updated to snapshot 20240514 with same issue.
Here is a screenshot of the white box displayed in top right of the screen. https://paste.opensuse.org/pastes/944b0bde86e1
Created attachment 874959 [details] 32 bit Tumbleweed after update to KDE P6 MEGARELEASE X11 session. This strange white box appeared in the right corner of the laptops display after KDE P6 Megarelease. It takes up 1/4 of the screen.
There have been new findings on this issue. I turned off compositing manually. In order to do this I edited /etc/xdg/kwinrc to include all of the following. [Desktops] Number=2 [Compositing] Enabled=false AnimationSpeed=2 - I set the default 'Display Manager' to LightDM (using on machine now) and have also tried with success XDM. Using > # update-alternatives --config default-displaymanager - I powercycled the machine. - I selected Plasma (X11) session in LightDM. Entered username and password. Desktop loads and the 'white box' is now *GONE*. - So far with the brief amount of testing here the machine seems to be quite stable with no taskbar or systray items slipping around. I no longer have a blinking cursor in Konsole. I am no longer able to start 'Kate' with sudo -E kate /file/to/edit but am able to workaround this by starting "Kate" in X11 session as root. - A curiosity that I have noticed now is that starting a Plasma (Wayland) session with LighDM. The "white box" returns only this time at the bottom right of the screen taking up 1/4 of the screen display as before. I have attached a screenshot also showing this. - I opened an instance of Dolphin up using Plasma (Wayland) and the box began flashing rapidly. It does not always do this though consistently it appears. - Switching to a (non-used and clear) workspace. Then clicking on the "white box" and then tapping enter does not cause anything to appear within the box from what I can tell. The "white box" seems to be live as I have Konsole set to display at the bottom of dolphin. Tapping enter causes the Konsole instance to rightfully take back over the screen. After about 1 minute of time the "white box" fills back up it's desired 1/4 of the screen. For some reason I would like to describe the situation as seeming that the "white box" is live and active *not* just stationary. - I would like to add that logging out of the session brings up a user prompt that asks for confirmation and those field descriptors are blank. I believe due to software rendering being turned off in '/etc/environment' to > # QT_QUICK_BACKEND=software See attachment image. - Software Rendering turned on after the KDE Plasma6 MEGARELEASE caused taskbar and system tray items to become misaligned and vacant or empty. Previously the software rendering was helping display characters in SDDM Display Manager as the field descriptors were blank in all the boxes. Switching to LightDM or XDM Display Manager(s), seem not affected by hardware or software rendering.

Notice the blank field descriptors. This issue I believe is caused by software rendering turned off. Cannot turn on software rendering now because taskbar and systray items will become disfigured.
Created attachment 874961 [details] White Box takes back screen in P6 Wayland Opening an instance of Dolphin. The Konsole at the bottom (pressing CR/Enter key) attempts to take back it's rightful screen area. The "White Box" after about a minute reclaims it's space automatically. - Clicking on the 'White Box' and tapping enter multiple times does not seem to change anything.
