Blank screen after leaving in background or in tray

[Martzy303]

Description After minimizing or in tray or even leaving in in the background of another window, it's blank screen, to make it work again I need to push the refresh button. What I noticed is that if I have whatsapp on my right half screen let's say, but I have focus on the window on the right side, I can see the new messages, if any, but as soon as I click on the window to reply, it goes white.

To Reproduce Steps to reproduce the behavior:

1. Open Whatsapp
2. Minimize in bar or tray or not focus it and wait for a while
3. Open it again

Expected behavior To work fine as before

[abclution]

Setting hardware acceleration to "never" (boo) fixes this it seems.

Seems to be working now, haven't tried with acceleration activated. I get the notifications in the list, but I don't see the preview like the other notifications, yet I have everything checked in settings.

// Have activated acceleration and the preview works, without grey screens for 2 days now, so it seems to be working as it should.
