wireview-linux 1.0.4.4 display issues

[jonathanhirschman]

A video capture shows various display related issues with the current release:

1.0.4.3 also had the same/similar issues:

(note: the artifacting seen when the GUI is switched from Light to Dark mode are video encoding related, not application related).

Some possibly pertinent information:

• The resolution of the monitor shown is atypical - 3840 x 2560
• GNOME's scaling is employed, 200% (although same issues are seen when set to 100%)
• Ubuntu 25.10
• Nvidia GPU

And this is why i neer target non LTS version of Ubuntu :/ I will see what I can do

Happy to do an early LTS upgrade just for you 😄 if you'd like to see if 26.04 helps things 😄

Thanks so much.

would still be fixing blind, let me see what I can do, for now cannot reproduce on 25.04

[emaspa]

The combination of symptoms, transparent/empty window at first launch plus later flashing on the overview tab points to a rendering-backend glitch rather than a layout or scaling-math problem (the fact that 100% scaling shows the same issues as 200% supports that). The likely culprit is Avalonia's Skia → EGL/GLX → Nvidia path under XWayland, which is a well-known weak spot of the stack. I can't reproduce locally so I want to narrow it down before shipping a code change.

@jonathanhirschman could you try two quick env-var runs against 1.0.4.4 and let me know which (if either) makes the window come up clean and stop flashing?

Force CPU rendering (slowest but most reliable):

AVALONIA_X11_RENDER_MODE=Software ./WireView2

Force GLX (skip EGL, which is Nvidia's usual troublemaker):

AVALONIA_X11_RENDER_MODE=Glx ./WireView2

If Software fixes it but Glx doesn't, we'll need a software-fallback path. If Glx already fixes it, a one-line code change to prefer GLX over EGL will land in 1.0.4.5.

Either way, no rush, I appreciate the testing!

[jonathanhirschman]

Tried both env-var runs, but nothing changes at all. Is wireview-linux seeing the values? I tried both the .deb version, and the pre-compiled package, no dice.

It'd be great if there was some feedback to indicate if it's using EGL, GLX or software rendering, perhaps at the command line. Thanks!

[emaspa]

I need a 25.10 vm to test, will do that asap.

Thanks for taking the time to run this down.
