I can Confirm this for the 4.4.8 and the Dec 20 5.1.0-prealpha (git 8d3bd3d) appimages on Debian 10. If you paint a small dot on the layer, then a tile of restored resolution will be created around that dot. This is shown in the attachment: Recovered Resolution Tiles.png. If you turn off then on the visibility of any layer, the entire image will have its resolution restored.

Actually, this is also visible if instant preview is turned off in the view menu.
The same issue happens with Move Tool, btw.
Git commit 7cbc18eaf16bb5653c1bfc44fc99085a36d48b94 by Dmitry Kazakov. Committed on 17/08/2022 at 07:43. Pushed by dkazakov into branch 'master'. Fix Canvas being stuck in lo-res mode after cancelling Move or Filter action Now when the update scheduler sees that a Lod0 stroke has been cancelled, it notifies the Resume stroke (via its filter) that the GUI should refetch image data for the Lod0 planes inside tiles.
