gl2d zoom turns background black

[alexcjohnson]

Plots using stackgl (heatmapgl, pointcloud...) get a black background when you start to zoom, and it doesn't go away after zoom. Prior to v1.32.0 it was a grey background and it did go away after zoom. Ideally it would turn grey only within the subplot area, but since these trace types are on the back burner I'd be happy with a return to the pre-1.32 behavior.

Presumably related to #2159 or #2238?

Two more observations/bugs on 1.37.1 (in addition to the black background noted above). I can move these to one or more new issues if you think they are sufficiently different.

Pan tool performs zoom action

• Refresh Pen
• Click on the Pan tool
• Drag on the plot and the zoom action is executed

Panning smears axis ticks

• Refresh Pen
• Click on the Pan tool
• Drag on the plot (this performs a zoom as above)
• Click on autoscale button
• Now drag again
• This time pan action happens, but the axis ticks get smeared.

thanks for the report @jmmease

I have been having the exact same issues (especially the black background and pan zooming) with heatmapgl. Is there any known fix/workaround?

Also seeing weird data issues (just straight lines and no actual data) when I pass through data for all axes, may be a bug in my code though as I need to test further.
