POKindle Fire hitches and texture corruption at 60 fps
text
Body
copied!<p>This appears to be a Fire-specific GPU issue, and I'd appreciate any help or suggestions.</p> <p>For the most part, my tower-defense game is able to run 60 fps even with dozens of enemies and towers all shooting every which way. However, at seemingly random times (even with nothing happening-- like sitting on the main menu) very evenly spaced 400ms hitches pause the game at an interval of around 2-3 seconds. Then suddenly the hitches will disappear and 16x16 pixel blocks of textures will randomly not render.</p> <p>These 2 glitches appear to be mutually exclusive and, like I said can be triggered simply by starting the game and navigating from the main menu to the level-select screen, where minimal resources are loaded and little game logic is happening. I use OpenSL for sound effects, and I noted that disabling sfx changed the hitch duration to 280ms.</p> <p>Then I manually forced the framerate from 60 fps to 30 fps (by inserting a sleep in the frame tick loop), and both glitches disappeared completely.</p> <p>Here is a screen cap that demonstrates the texture not rendering. This bug happens in all 32-bit render surfaces regardless of depth/stencil values and whether color-clear is on or off.</p> <p>Thank you!</p> <p>EDIT: Actually, apparently the texture flicker happens at any framerate, however, somewhere under between 40 and 45 fps the 400ms hitch goes away. </p> <p><img src="https://i.stack.imgur.com/MtLpJ.png" alt="level select screen"></p> <p><img src="https://i.stack.imgur.com/Wr8md.png" alt="main menu"></p>
