Fairly frequently, but not 100% of the time, when a waveform is moved to another viewport a waveform in the original viewport (not the one being moved) stops displaying correctly and the console is spammed with OpenGL error 502 (GL_INVALID_OPERATION).

No steps to trigger the issue reliably on cue are known, however if you keep moving waveforms between views it will eventually show up. All recently observed incidents corrupted the bottom waveform in the original viewport, however it is not known if this is always the case.

Corrupted waveforms can be restored by moving them to another viewport, then (optionally) back to their original location.

Observed while deleting clock recovery protocol decoder.

I have finally built with success glscope using scopehal-cmake on VirtualBox XUbuntu 18.04.02 LTS but I have an error when I launch the glscopeclient it seems there is a missing css file see error below:

hydra@hydra-VirtualBox:~/scopehal-cmake/build/src/glscopeclient$ ./glscopeclient

I confirm styles directory does not exist after build so styles/glscopeclient.css is not found

Right now the ProtocolDecoder field colors are initialized statically at start and can't be changed.

Most of the code is there, just need to be able to turn it on and off.

For example: protocol decoders that want a digital channel should suggest thresholding analog channels at the 50% level, then create the thresholding filter automatically when the dialog exits.

We should support both old-school CSV as an interchange format and a protobuf-based (?) native serialization format.

File format design is nontrivial because channels may be sparse, have different sampling rates, etc. We should also save protocol decoder config in some way.

Observed on a HDO9204. Need more work to diagnose.

Right now, if the user closes the protocol analyzer dialog there's no way to get it back...

Should be some way to click on part of an eye pattern (e.g. mask failure) and see a waveform exhibiting that behavior.

Text decode overlays seem to be fine, but digital waveform overlays blow away the channel name and make it unreadable.

148.5M is much easier to type correctly than 148500000.

Eye, trace, etc rendering should be done in derived classes rather than putting everything in one class.

We've gone back and forth between a fixed timer and "never". What's the best option? Maybe have a button somewhere to explicitly re-sync state?
