Laggy Performance on Linux Mint

[SpeeQz1]

Bug Description

When trying to do any action inside the Pinta AppImage the whole application just performs very poorly and lags. This includes making a selection, drawing, erasing, etc.

System Information

• CPU: Intel i7-14700KF (28) @ 5.500GHz
• GPU: NVIDIA GeForce RTX 4060 Ti
• OS: Linux Mint 22.2 x86_64 (Cinnamon 6.4.8)
• AppImage Launcher: Gear Lever

Did you verify that there's no performance issue in other types of packages and which packages you also tried?

[SpeeQz1]

I've tested it with the Flatpak package on version 3.0.4 and it works without a problem.

You are not watching the repo, so notifying

Just guessing, it's maybe due to OpenGL, GDK_BACKEND which works worse for Nvidia than Vulkan, or maybe there's somehow no GPU acceleration for Nvidia?

Thanks, wouldn't have noticed.

Does this lag on your system?

@Samueru-sama no problems running the demos

And just to be sure, the glxgears one says that it is using your nvidia gpu right?

If that's the case I'm not sure what could be wrong here, run the pinta appimage this way:

APPIMAGE_DEBUG=1 /path/to/pinta

And send the log file, it will be located in HOME.

@Samueru-sama Here is the log:

Pinta-3.0.4-1-anylinux-x86_64.AppImage-debug.log

@Samueru-sama Here is the log:

Pinta-3.0.4-1-anylinux-x86_64.AppImage-debug.log

Alright the nvidia driver is loading without problem, but then you have this error:

libEGL warning: pci id for fd 93: 10de:2803, driver (null)
pci id for fd 95: 10de:2803, driver (null)
kmsro: driver missing
libEGL warning: egl: failed to create dri2 screen

This looks like a bug in newer versions of mesa which are shipped in this AppImage.

Do the following, extract the appimage with --appimage-extract, then run the following:

rm -rf ./AppDir/share/glvnd ./AppDir/lib/dri ./AppDir/lib/gbm ./AppDir/lib/vdpau
rm -f ./AppDir/lib/libEGL_mesa*
./AppDir/sharun -g
./AppDir/AppRun

Hopefully it launches, do you still have lag?

Another thing I noticed in the logs is that the app is looking for a libGLX.so.1 lib.

But this lib is not bundled because it does not exist in archlinux which is where this appimage is made, instead the lib is called libGLX.so.0:

What happens if you symlink libGLX.so.0 in the AppImage as libGLX.so.1?

[SpeeQz1]

@Samueru-sama no need for the libGLX symlink, your first steps with --appimage-extract fixed the error.

Side note: I had created a folder with an empty space between the name so something like Test Folder and when trying to run the commands it didn't work out and seems to have stopped at the Test part. Changing it to Test-Folder fixed the issue.

@Samueru-sama no need for the libGLX symlink, your first steps with --appimage-extract fixed the error.

Cool, but would be good to check if the libGLX symlink fixes the issue as well, because I have no way of downgrading mesa here.

Also test setting these env vars as well:

__NV_PRIME_RENDER_OFFLOAD=1
__GLX_VENDOR_LIBRARY_NAME=nvidia
LIBGL_KOPPER_DRI2=1

Also test with MESA_LOADER_DRIVER_OVERRIDE=zink.

@Samueru-sama exported the appimage again and found the only change that needs to be done is for the env variable to be modified LIBGL_KOPPER_DRI2=1 for the app to work without lagging.

Same is applicable for the .AppImage too.

Alright in that case the solution is running --appimage-add-env 'LIBGL_KOPPER_DRI2=1'.

This also means this is not a bug but rather mesa wants to enforce DRI3 moving forward, which very likely your version of the nvidia driver does not support.
