White Screen on Launch #70

Closed wrkzk closed 2 years ago

wrkzk commented 2 years ago

Describe the bug When I launch the jar file using the command line, it appears to start up normally without any errors, but the window is white and displays nothing.

Expected behavior That the interface would display.

Desktop (please complete the following information):

Hi! I'm sorry that you are having that issue.

Two things: Which version of EOCV-Sim are you using?

And, could you provide the logs? You might be able to see a "lasterror-eocvsim.log" file, or a "crashreport-blablahblah-eocvsim.log" in the same folder where the jar file is located.

If you don't see such file, can you run the sim using the console and copypasting the messages once it reaches to the blank screen? e.g

java -jar EOCV-Sim-X.X.X-all.jar

Hope that's clear

I just tested this again with the most recent release, 3.3.2. I am using openjdk 17.0.1. I have pasted the output from when I run the jar from the command line. Thanks so much for your help!

Hm, that doesn't look like it's a problem on the eocv sim side since UI initialization is happening correctly (see the "loading future icon" messages at different points, which means that the UI is correctly loading and requesting the required icons).

Though, for arch Linux specifically i found something on the wiki regarding to java UI apps: https://wiki.archlinux.org/title/Java#Gray_window,_applications_not_resizing_with_WM,_menus_immediately_closing That might be the problem? I have never used arch honestly so I'm not sure but i hope this helps!

Thanks so much for the wiki link! Sorry to bother you with an unrelated issue. Running export _JAVA_AWT_WM_NONREPARENTING=1 before running the program fixed it.
