OpenMarine - Black OpenCPN window after 5.2 update

I have latest version of Openplotter running on RPI4 and updated my OpenCPN from 5.0 -> 5.2 today. As a result,
- OP starts normally, checking the system
- OpenCPN window appears but it is black, despite of 5 dots on the right. it says OpenCPN 5.2.0 at the top and has SOG and COG at the bottom
- nothing else appears on the window. before the update I had Dashboard in use
- when restarting, OpenCPN offers to start if safe more, but the result is the same
- when I try to kiill the OpenCPN window, I need to hit the 'X' in the top right corner twice to kill the window

I did apt update and upgrade. According to Settings (2.3.0) all OP apps are of the latest version.

All ideas warmly welcome!

I did uninstall and reinstall opencpn. Still the same black screen. When I start open cpn from command line, I get:

(opencpn:3165): Gtk-CRITICAL **: 18:59:52.649: IA__gtk_window_resize: assertion 'height > 0' failed

Any ideas? Before updating OpenCPN 5.0 was working just fine.

Have you tried removing the folder /home/pi/.opencpn or you can just rename it and open opencpn again to test

I had OpenCPN 5.0 installed and renamed .opencpn folder and started OpenCPN -> 'clean' .opencpn-folder.
Then I upgraded 5.0 -> 5.2 and started OpenCPN resulting the same error

(opencpn:5910): Gtk-CRITICAL **: 21:07:10.246: IA__gtk_window_resize: assertion 'height > 0' failed

Then I renamed the .opencpn folder again and started OpenCPN 5.2 .... resulting the same error again....

Anyone else having the same error?

Since 5.2 did not start I reverted back to OpenCPN 5.0. it starts normally, but when started from command line it yields an error which may be related to the error I copy pasted in my previous post

(opencpn:3020): Gtk-WARNING **: 21:59:00.328: gtk_widget_size_allocate(): attempt to allocate widget with width -5 and height 26

Any thoughts?

that gtk-warnings are expected and not related to your issue.
no more errors?
are you sure you have a raspberry 4?
is opengl enabled in your system?

Thanks Sailoog for your reply!

I did sudo apt-get update and upgrade. Then I tried installing 5.2 again - the same results. I went back to Opencpn 5.0.
I did check the 'Use OpenGL' checkbox in OpenCPN. Should I enable it some other way?

Now (perhaps due to enabling OpenGL?) I do have more more and different errors (previously only the one I reported), see below.

Yes, I have raspi4.

PS. I noticed that when I open the 'Screen layout editor editor' it behaves similarly than Opencpn 5.2: a window opens, but is nonresponsive and cannot be killed....

Since the original error did not appear anymore, I tried to install OpenCPN 5.2 again.

The results (see the link below) instead of a black screen, I now have a blue screen. I can see the boat icon, but the program stays nonresponsive and hard to kill....

The same error:
