No games will display. (White screen)

[corsair]

Hello there,

When attempting to launch any Gameboy games, the emulator window will appear, but will remain as a white screen. I've attempted three different Gameboy Color games all to the same effect, in addition to a Game Boy Advance game.

Additionally, the emulation window appears to lock up and ignore further user actions including attempts to close it.

Thank you for your time.

These are some lines copied from Console.
Mar 10 20:46:28 Anchor OpenEmu[82905]: objc[82905]: Class IKCGRenderer is implemented in both /System/Library/Frameworks/Quartz.framework/Versions/A/Frameworks/ImageKit.framework/Versions/A/ImageKit (0x7fffac9dc5f0) and /Applications/OpenEmu.app/Contents/MacOS/OpenEmu (0x1007a57e8). One of the two will be used. Which one is undefined.

Steps to reproduce

1. Launch any game.

Expected Behavior

Game launches properly and displays the expected output.

Observed Behavior

Upon launching any game, the emulator display area will be completely white. Also attempting to relaunch the game will not have any effect.

After launching the game, I am also unable to close this window. Even clicking on Stop/Quit will be ignored. I am forced to force quit OpenEmu to get any windows to disappear.

Debugging Information

• OpenEmu Version: 2.0.8
• macOS Version: 10.14.3 (macOS Mojave)

Haven't given enough to go on (random copy and pasted Console output is useless -- could use the lines from as it actually happens), but sounds likes the core plugins crashed. First try games in the Homebrew tab, especially ones in the Game Boy Advance section and see if those work.

Sorry for the lack of logs or output. I wish it would crash fully as to provide a full log, but sadly that hasn't been the case. I just attempted to run "Spout" via the Homebrew tab and it resulted in the same issue.

Here is 100% of the Console logs from the moment of attempting to launch the game:

Edit: Also, just became a patron. Thanks for always providing one of the best game emulator platforms. I've been using OpenEmu on and off for years.

There is nothing useful in that log -- it's just TCP traffic. You should filter Console.app for "openemu" and then retrieve output as you try to launch and close a game.

Here's attempting to launch a game. Appears it finally captured an error.

Surprisingly, nothing is logged when attempting to click on the close button + confirming window.

[clobber]

Nothing there, that isn't surprising. Try switching filters if you're not using Nearest Neighbor or Pixellate. Also close down all other apps to try to narrow down if there is a conflict. Also try a machine restart. I've seen issues on Mojave with other apps running that are using GL that will cause video to not render in our app. As it stands now, we cannot replicate your problem.

[corsair]

I'll restart shortly and attempt to run it with no other applications running. I have three monitors attached, but not sure if that could be a potential issue.

If it continues to occur, I will get a video of it posted shortly. Sorry for the trouble thus far with this issue.

[clobber]

Yes, a restart at this point would be the best course of action. Narrowing down a problem with specific hardware (such as multiple monitors) or application is also recommended. A video of the app displaying a white screen isn't going to be useful to us, though.

[corsair]

Seems to be working well after a restart. The good ole' turn it off and back on. I'm going to self-close this issue, but may reopen it if the issue occurs again due to some kind of conflict with other applications.

Thanks for your time. @clobber
