[Tracker] Sometimes it "forgets" icons until redraws are needed

[bipolar]

I've been noticing this since... at least 2/4 months I guess. It is sporadic, and I usually forget to take a screenshot before the missing icons are redrawn properly (draging any other window in front of the missing icons fixes it, for example).

Attaching a screenshot of the sporadic, but frequent enough to notice, "missing icons in Tracker" I see on my system (64 bits, hrev56112 and hrev56140, but has been here in nightlies for several months at least). .

Don't remember seing that on beta3.

Edit: And... just after minimizing Webpositive, I saw some missing icons on the Desktop :-) As usual, a quick forced redraw fixed it.

Edit 2: I have the "Generate image thumbnails" Tracker option disabled, in case that changes something.

Edit 3: Particularly bad day for Tracker on my PC today it seems: Also got "partialy drawn icons on Desktop". Will attach screenshot.

FWIW, I frequently get those "missing" icons on the desktop after minimizing a window that was previously maximized.

Happens with the Radeon HD driver (on a Radeon 3000 iGPU) and while using the VESA driver (now on an nVIDIA GT 1030).

I'm attaching a short clip of me "repainting" the icons using a window as brush, just in case it might shed some light on what could be the problem.

I haven't seen this bug again in quite a while now (at least a month, I would say), even after several hours a day of usage.

Now on hrev56441, but even before that one this bug seems to have vanished for me.

I guess this ticket could be closed.

Quite possible the icon sizing refactors fixed it. Thanks for checking!
