Video Playback lagging since mesa 19.2.0 update on Intel 1st Gen Core Ironlake Mobile GPU.
i have installed LibreELEC Nightly builds on an old Acer 1830 laptop with Core i3 380UM processor which is connected to 1080p TV via HDMI,since mesa 19.2.0 update videos at 1080p resolution are lagging. a 25fps or 30fps 1080p video would play like 10fps video, VAAPI acceleration is disabled so it's CPU decoding, however if i switch resolution to 1366x768 then videos would play smoothly. the last working build before mesa 19.2.0 which did not have the aforementioned issue is 0924 and it has mesa 19.1.7 which is working perfectly fine,the problem starts from build 0925. also noticed lag in UI as well.
