Empty window on Pine Phone

[sagb]

I try to run OpenHantek on Pine Phone (arm64). It starts, some grid lines flash briefly (seems like borders of widgets, no content), then it ends up showing black window.

Tried with no success:

• window managers: dwm, ratpoison (I long used OpenHantek in ratpoison on laptops without problems)
• downgrade to 3.1.1
• --demoMode, --useGLES, --useGLSL120, specific --font

Computer environment:

• OpenHantek version: 20220101 - commit 944 (3.2.5-6-g27eb8c5). Also tried 3.1.1.
• OS: Linux
• Distribution, version: Debian bookworm (testing)
• Video hardware: Mali400
• OpenGL version: 2.1 Mesa 21.2.6
• Qt version: Qt 5.15.2
• C++ compiler version: gcc 11.2.0

Scope device:

• Device: Hantek DSO 6022BL (--demoMode doesn't work either)
• Program top lines: OpenHantek6022 (20220101 - commit 944), use device "DSO-6022BL" serial number "CE24011FCD29"
• Input signal: N/A
• Probe setting: N/A

Additional context

Tried separate X11 client and server:

• run OpenHantek on Pine phone, displaying to remote X server
• run OpenHantek on laptop, displaying on Pine X server

Surprisingly, both work. Combination "executable and X server on Pine phone" still fails.

Sometimes random mouse click on black window reveals a widget: pine-openhantek-1 pine-openhantek-2

Please play around with the OpenGL version as I wrote some time ago. Then you could try also the option --useGLSL150.

[sagb]

MESA_GL_VERSION_OVERRIDE=3.2 MESA_GLSL_VERSION_OVERRIDE=150 OpenHantek -i --useGLSL150 MESA_GL_VERSION_OVERRIDE=3.2 MESA_GLSL_VERSION_OVERRIDE=150 OpenHantek -i MESA_GL_VERSION_OVERRIDE=4.5 OpenHantek -i MESA_GL_VERSION_OVERRIDE=1.0 OpenHantek -i

All failed.

Found a workaround (but slow - unusable): forwarding X11 calls via ssh:

ssh -X localhost OpenHantek

No more activities, I will close. We can reopen if someone is willing to support.
