Output glitch when running xfce4-session with zink+turnip on Termux-x11

[hansm629]

Host Device : Galaxy S23 Ultra, Galaxy Tab S8+ 5G, Galaxy S20 Termux : PRoot-Distro Ubuntu 22.04 LTS Xwayland XFCE4-SESSION 4.18

XFCE4 with GALLIUM_DRIVER=virpipe on virglender-android, it will show fine If run XFCE4 with zink+turnip, there is an output glitch. :(

The command to execute virglender-android is as follows.

$ virgl_test_server_android & 
$ XDG_RUNTIME_DIR=${TMPDIR} termux-x11 :0 -ac & 
$ proot-distro login ubuntu --user id --shared-tmp --no-sysvipc
$ export DISPLAY=:0 GALLIUM_DRIVER=virpipe MESA_GL_VERSION_OVERRIDE=4.6COMPAT MESA_GLES_VERSION_OVERRIDE=3.2
$ dbus-launch --exit-with-session startxfce4 &

It is well represented by virgl in XFCE4 GPU info.

Also, it is written as virgl even if it is executed without glmark2 environment variable in the terminal.

I have compiled and built the Freedreno turnip kgls driver.

When running a program with environment variables in a terminal zink+turnip is applied well and vkcube is running well

but Problem occurs when running XFCE4-SESSION.

The command to execute zink+turnip is as follows.

$ XDG_RUNTIME_DIR=${TMPDIR} termux-x11 :0 -ac & 
$ proot-distro login ubuntu --user id --shared-tmp --no-sysvipc
$ export DISPLAY=:0 MESA_LOADER_DRIVER_OVERRIDE=zink TU_DEBUG=noconform MESA_VK_WSI_DEBUG=sw VK_ICD_FILENAMES=/usr/share/vulkan/icd.d/freedreno_icd.aarch64.json
$ dbus-launch --exit-with-session startxfce4 &

Issues that occurred in XFCE4-SESSION executed with zink+turnip are

**1. Top UI not displayed

2. Bottom panel UI is broken and displayed
3. Application does not display title UI**

GPU information is displayed well by turnip.

glxgears, glmark2, vkcube, etc. also run well in the terminal. Is there a way to fix the XFCE4 output glitch?

Adreno650, Adreno730 and Adreno740 all have the same symptoms.

Probably a problem of zink or turnip. X server can not affect this, only mesa or its components can.

Also, it is written as virgl even if it is executed without glmark2 environment variable in the terminal.

Probably some problem of your environment. X server has no ways to enforce using virpipe.

I am pretty sure with vncserver you will have the same result, not a problem of termux-x11.

You should ask this question in mesa support forum.
