Krunner redraw glitch #70

Open adriaandegroot opened 6 years ago

With no other windows open, hit alt-space to open krunner. Type in a search string -- I used calc here, but qua will also do enough of a search. I had networking / wifi enabled. There are several sections of results returned by krunner. Hitting ESC when the first section is shown, but before Discover results are in, leaves the krunner results drawn on-screen as a glitch.

Here the red arrow labeled 1 shows where krunner was before it was canceled. Arrow 2 points to the drawn results from krunner, which are still showing even after canceling krunner. The draw results disappear when something else is drawn, e.g. when another window gets the focus. That's why it is important to have no other windows showing, or to have them well-down on the screen and un-focused, to trigger this redraw issue.

Sometimes -- more rarely than the scenario above -- hitting ESC when the Discover results have been show, also leaves drawing artifacts behind. Again, in this screenshot (1) points to where krunner was, and (2) to the graphical artifacts left behind.

so is a piece of window that stays on screen because an area wasn't redrawn? is the qt patch about sending the proper damage area landed?

If you mean my one with net_wm_sync, yeah. But I don't think it'd be relevant here. If a window is unmapped the client shouldn't need to send anything else.
