Bug - Blinking window #108

Open leoneivaw opened 3 years ago

leoneivaw commented 3 years ago

First of all thanks for this great software. Parachute looks like doing some action when running on background. Some windows start to blink or move some areas.

It happens randomly.

Thanks!

That behavior is indeed odd. Judging by the videos you have shared, it seems like the "blinking" issue is related to window content, and not Parachute. Some troubleshooting steps I can think of:

  1. Try running kwin_x11 --replace & in a terminal or directly in Plasma Search (KRunner; press Alt+Space to activate it). Does the blinking persist after that?
  2. Try disabling Parachute in System Settings > Window management > KWin scripts. Run the above command to refresh KWin. Is it still blinking? If it is, you can re-enable Parachute, as it is not the source of the issue.
  3. It looks like you have a laptop. If you have access to other devices that could run Plasma, please try on those too. I suspect that it is a hardware-related problem, more specifically keyboard or touchpad. If you can, try disabling these on the laptop, and connecting external peripherals.
  4. If none of the above, it might be a graphics driver or compositing issue, but that it unlikely, unless you have seriously messed with either of these. Please provide more information on what applications have this problem.

This was also happening on my machine with an Intel graphics card. After I replaced it with an AMD Radeon the problem is gone. The smoothness of the animations also improved a lot after this change. So I think that maybe the problem is related to the Linux support of Intel drivers.

I will put this info as a note in the README file of the project. I'll just wait for some more feedback about these differences here.

EDIT: This is related to #61.

I had already done this test and the problem only happened with Parachute enabled.

It happens all the time and is annoying. And if we close parachute the problem is gone. That simple!

I have found the solution for my case and i was just waiting more 1 or 2 days to confirm if the problem is really solved to give a feedback.

I renamed the file ~/.config/plasmashellrc and the system has created another one. For while there is no issue.

I was trying to solve another problem. My desktop was locked. I coudnt make any change or create widgets. I dont know if the issue was caused by parachute. But now everything is running fine.

Thanks
