Emulator Issues #12761
Black flashing when pressing or releasing turbo button with Vulkan in Exclusive Fullscreen in my laptop's 120hz screen
Game Name/Game ID/MD5 Hash
All games I tested are affected, even the GC and Wii System Menu
What's the problem? Describe what went wrong.
The moment I press the turbo button to disable the "emulation speed limit", during a second the screens blinks with black (sometimes showing part of an outdated frame in the process). The same brief blinking happens when I release the button to limit the speed.
This only happens on Vulkan (OpenGL, D3D11 and D3D12 work fine), in exclusive fullscreen (windowed or borderless fullscreen are fine) and with my 120hz laptop screen (if I connect my laptop to my TV, it runs fine).
What steps will reproduce the problem?
Run any game in (exclusive) fullscreen with the Vulkan backend in a high refresh ratio monitor (I only tested 120hz, I suspect other refresh ratios may be affected).
Is the issue present in the latest development version? For future reference, please also write down the version number of the latest development version.
Is the issue present in the latest stable version?
There wasn't a Vulkan backend in the latest stable.
If your issue is a graphical issue, please attach screenshots and record a three frame fifolog of the issue if possible. Screenshots showing what it is supposed to look like from either console or older builds of Dolphin will help too. For more information on how to use the fifoplayer, please check here: https://wiki.dolphin-emu.org/index.php?title=FifoPlayer
[Attach any fifologs if possible, write a description of fifologs and screenshots here to assist people unfamiliar with the game.]
