Rpcs3: Main window does not appear or freezes when too many games are installed and freezes when grid view is used on Linux

[Sonickyle27]

Quick summary

It appears that if too many games are installed in RPCS3 on Linux, the main window does not appear when running RPCS3, and when I install certain new games the GUI will freeze.

Details

I have the following games installed/set up in RPCS3:

• NPEB02021
• NPEB02026
• NPEB00777
• NPEB01083
• BLES02070
• NEPA00241
• NPEA00324
• NPEA00291
• BCES00052
• NPEA00088
• NPEB00879
• NPEA00057
• NPJB00785

This is how this list appears:

From here, if I click the grid button, the main window freezes, and nothing else happens other than the terminal being spammed with libpng warning: iCCP: known incorrect sRGB profile messages (I'm pretty sure this is unrelated though).

If I then try installing Bejeweled 2 (NPEA00124), it successfully installs and the windows remains responsive. If I then remove that game, reload RPCS3, and try installing Bejeweled 3 (NPUB30773), the window becomes unresponsive after the game installs. I can see the game's folder in dev_hdd0, but if I try running RPCS3 after this happens, the main window never appears but the process remains running.

I've tried using a brand new RPCS3 config folder and the more games I install into this new config folder, this issue crops up again.

I'm running version 0.0.10-10506-717e851a9 but I've also tried 0.0.10-10468-dcf5c06d6 and the same issue appears.

If I remove the ICON0.PNG file from the game's folder that causes the issue with the RPCS3 window not showing up when running , the issue actually disappears, so I believe it has something to do with that file. Heck if I swap out the icon for another game's ICON0.PNG, like the one from NPEB02026 it correctly shows up and the window appears.

EDIT: If I remove the alpha channel from the icon of a game that causes this issue (which have a transparent icon), then save it, this is enough to make this issue go away, however I have other games installed with transparent icons that don't show this issue...

Logs provided nothing, needs gdb backtrace

[Sonickyle27]

Hopefully this is enough. I am completely unfamiliar with how gdb works. This is from me loading up RPCS3 while a game that causes the window to not appear is installed.

Does it happen with pre built appimage from CI?

[illusion0001]

From lib warning it seems it fails to decode proper color space for those transparency icons

[Sonickyle27]

I've never used any of the appimage builds before. I will give the latest the try when I am next at my computer.
If it's worth mentioning I upgraded my qt packages to version 5.15.0 a few days ago. Before then I wasn't seeing this issue so I think that may be related, so I'll see if I can downgrade that too.

Qt 5.15 seems to have issues with RPCS3

[Sonickyle27]

The AppImage version opens without issue and the grid view does not freeze the window either! I can see it uses Qt 5.14.2.
There is also no libpng warning: iCCP: known incorrect sRGB profile spam in the terminal.

[Megamouse]

Closing. Qt 5.15 is not supported by rpcs3.

[Sonickyle27]

Is there plans for support for it in the future? I tend to avoid AppImages whenever I can and this is the only issue I'm getting with running RPCS3 with that version of Qt installed.

[Megamouse]

Yes. But for that I'd either have to write a workaround for the nonworking versions or we'll have to hope that a Future version of Qt fixes their code.

[Megamouse]

Okay, good news.
Apparently the issue was already fixed in Qt and is scheduled for version 5.15.1
