Created attachment 947239 [details] Dock is hidden, but the amount it slid down appears as band on the screen. This covers other windows, etc. Description of problem: Due to unknown circumstances, plank auto-hiding/smart-hiding causes banding to show up on the screen. During this time, small white boxes appear around the notifications on the dock. It looks like this might be related to transparency in the dock, or something similar. Version-Release number of selected component (if applicable): plank-0.5.0-4.fc20.x86_64 How reproducible: 100% of time, when it happens. Steps to Reproduce: 1. Start plank. 2. Wait. 3. Banding occurs. 4. Kill dock to make it go away. Actual results: Wide band the size of the dock appears above dock. Expected results: Not that. Additional info: Will provide screenshots.

Hmm, what video drivers are you using also can you share $HOME/.config/plank/dock1/settings?

Sure, it's a Dell E5530, using an on-board Intel HD chip, i915 driver: 00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09) drm_kms_helper 58041 1 i915 drm 291361 7 i915,drm_kms_helper i2c_core 55486 5 drm,i915,i2c_i801,drm_kms_helper,i2c_algo_bit
I haven't noticed any specific action that I'm doing that is causing that to happen, but just over the course of the day while using it, I notice that when I see the banding that slides up and down as the dock moves up and down, the boxes also appear. Kill and restart of the dock resets this for awhile. I've also noticed that when the dock is in panel-mode, this doesn't seem to happen, banding or boxes.
Created attachment 947667 [details] GNOME Screencast showing example. As an update, I had this issue pretty much straight out of the gate this morning, and even killing/recycling the dock didn't seem to remove it, so now I'm thoroughly confused as to what might be causing it outside of video handling issues. To get a better idea of what I'm referring to, I've included a webm screencast.
Can you see if it reproduces with the latest version of plank? I have rpms built here: https://jknife.fedorapeople.org/plank/
Updated, running it now; I'll wait a few days and report back. Thanks.
Sorry to say, but it's still got the issue; launching Plank from the command line doesn't seem to indicate anything special in the output, and I can't seem to find any common thread that induces it. Is there a debug option I can turn on that produces a more verbose output, in the hopes of capturing something useful?
My bad; I'll do some experimenting with -dv flags to see if anything meaningful comes out of it.
Created attachment 951125 [details] Plank (plank -dv) output capture. Running plank -dv, at some point near the bottom (I wasn't paying acute attention), it returned to the banding/boxes. I don't have an exact line, though.
Hmm, so talking to upstream he said this is sometimes related to updating drivers. So can I get the output of "uname -r ; rpm -q xorg-x11-drv-intel"?
Also when the problem manifests itself can we get the output of "cairo-trace --flush --no-callers plank" cairo-trace is in the cairo-tools package.
3.16.6-200.fc20.x86_64 xorg-x11-drv-intel-2.21.15-7.fc20.x86_64 cairo-tools is installed, I'll get that attached whenever I see it next.
Created attachment 951200 [details] cairo-trace Ran into it immediately on launch, clicked a few dockitems, raised and lowered the dock (with band), and then quit it.
Ok, can you test out this version https://jknife.fedorapeople.org/plank/plank-0.7.1-2.fc20.x86_64.rpm ?
Created attachment 952251 [details] Yellow Boxes Installed your updated package that day and have been running it since. I haven't seen any of the previous banding effects, though now it seems that each of the icons has a yellow box around it, pretty much all the time. (See attached). I have done a cairo-trace and will attach that next.

With default repo-provided plank-0.7.1-1.fc21.x86_64 in Fedora 21, I am no longer seeing this issue.
