Finalize adoption of Windows/Arm64 architecture

[gzotti]

Thanks to a device donation from Microsoft we have finally an Arm64 (Surface laptop) to test and finetune some parts of the program which we could not test so far.

I observed the following issues in 25.4 where the Arm/64 Windows download differs from Intel x86_64 Windows, and thought of the following areas to investigate. Please add where you see need.

• Upgrade gray splash (indicating "unfinished"). This should be fixed last!
• Sign the installer
• Make ShowMySky available for self-compilers.
• Make ShowMySky available in the package.
• Test Star catalog download
• Test DE4xx ephemerides
• Test Spout
• Test Speech output
• Test Media output
• Test RemoteControl
• Test RemoteSync
• Test online DSS and HiPS
• Test offline DSS and locally installed HiPS
• Test Telescope Control plugin: Simulator
• Test Telescope Control plugin: LX200 native/Serial.
• Test Telescope Control plugin: ASCOM7.1 with simulator.
• Test Scenery3D
• Test rendering quality of Sun (texture size) and esp. Moon.

Can you show the output of wglinfo or a Stellarium log from this device (or both)?

[alex-w]

Yeah... What about specification of device?

[gzotti]

Sure, these were scheduled for today. I am still configuring, downloading stuff, configuring GH access, preventing overnight auto reboot, etc...

Observation: my latest large spherical landscape (16kx8k) works, but an accompanying lightscape must be rescaled to 8kx4k, else GL is out of memory. But I'd need to test a few Intel-only systems, I think many "business" systems won't accept textures >8k.

else GL is out of memory

Ironic, given this:

[WGL] OpenGL GPU memory: 16292 MiB

Do you actually get GL_OUT_OF_MEMORY?
