OpenGL graphics corrupted on Ubuntu 23 04

[choupette-change]

Question: Have you tested Sdrangel vs Ubuntu 23 04?

[robbietee]

Yes. Compiled from source on Ubuntu 23.04. Spectrum windows show the window or desktop behind as if the window is transparent then it gets progressively weirder and not usable.

Screenshots didn't catch the issue correctly. The actual screen looks more like this:

Graphics issues aside, functionality is good. I found no issues with:
Rtl-Sdr

Channels:
ADS-B
AIS
AM
Broadcast FM
DAB
NFM
Packet
Pager
Radiosonde

Features:
AIS
APRS
Map
Radiosonde

I've never had much luck with digital modes on any version. A "Configurations Download" Page would be useful.

Thanks, Rob M6RXT

Not an issue with Ubuntu 23.04 nor the code. It compiles and wirks:

I see the same problem, so presumably something graphics driver / opengl related.

Make sure you start compiling from scratch. The drivers have probably been upgraded this is to make sure the current version is used.

I compiled from scratch on a fresh install and still have the issue. I will start researching.....

I just compiled the Qt openglwindow example (from Qt Creator) and this shows a similar corruption. So I suspect it's a Qt/Graphics driver issue.

[robbietee]

It's so annoying. I don't know why I bothered with the 23.04 "upgrade". Having said that, I haven't found any other issues with it....yet.

If you can build from source, give that patch a try - it fixes it for me.
