Short description of error
Non stop drawing after moving mouse between motion tracker editors

Exact steps for others to reproduce the error
During testing #67832 (Background images ignore View transform) I came across the issue that the motion tracker editors got into a state where they were always redrawn. I wasn't able to get blender back to its correct state.

You need a debugger to test this. I used renderdoc.

colorspace_example.blend

Open the attach scene.
Move mouse from the bottom movie clip editor to the top movie clip editor.
now a movie clip editors is in a state where its redrawn and you're not able to get out of the state.

possible performance issues.webm

I wasn't able to detect this with other mouse movements.

Part of the problem is this UI_view2d_sync called within a drawing function, causing a kind of infinite loop -> clip_dopesheet_draw.c$319

Seems I can not reproduce the issue with Renderdoc 1.7 and Blender ed4647b5d7. Is it still an issue?

Is the UI_view2d_sync called from the draw function is a culptrit, then I don't think it is valid to say it is a movie clip issue: same code i used in NLA and Dopesheet.

I can't reproduce the problem anymore.
Something must have fixed it.
So calling UI_view2d_sync with ED_region_tag_redraw_no_rebuild within a drawing function is not that serious.
